         3 . A tube electroforming method comprising the steps of: forming an electrodeposit material or a surrounding material around a thin wire material by electroforming; and removing the thin wire material from the electrodeposit material or the surrounding material
 characterized in that the thin wire material is removed by pulling the material from one end or both ends, deforming the material so as to reduce a sectional area thereof, and forming a clearance between the thin wire material and the electrodeposit material or the surrounding material, following by gripping and pulling the thin wire material, sucking the material, physically pushing away the material, or blowing a gas or a liquid to push away the material.   
     
     
         4 . The tube electroforming method according to  claim 3 ,
 characterized in that an amount of an end-portion-side electrodeposit or surrounding material to be formed on the thin wire material is increased.   
     
     
         5 . The tube electroforming method according to  claim 3 ,
 characterized in that a deformation amount of a lateral distortion at a time when the thin wire material is pulled and extended outwards is 5% or more of the sectional area.   
     
     
         6 . (canceled) 
     
     
         7 . The tube electroforming method according to  claim 3 ,
 characterized in that the thin wire material including a conductive layer disposed on an outer surface thereof is used, and the thin wire material is removed so that the conductive layer remains on an inner surface of a tube by electro forming.   
     
     
         8 . The tube electroforming method according to  claim 3 ,
 characterized in that the thin wire material is used in which at least two conductive layers constituted of different materials are formed on an outer surface of the material, the electrodeposit material or the surrounding material is brought into close contact with the outer conductive layer of the thin wire material, and the thin wire material is removed so that the inner conductive layer remains on an inner surface of the tube by electroforming.   
     
     
         9 . The tube electroforming method according to  claim 3 ,
 characterized in that an inner shape of a hollow portion formed by removing the thin wire material from the electrodeposit material or the surrounding material has a circular sectional shape or a polygonal sectional shape.   
     
     
         10 . The tube electroforming method according to  claim 3 ,
 characterized in that the tube by electroforming includes a plurality of hollow portions formed by removing the thin wire material.   
     
     
         11 . The tube electroforming method according to  claim 10 ,
 characterized in that a partition wall member formed by disposing a conductive layer on an outer surface of an insulator is disposed between the hollow portions, whereby each portion forming a periphery of each hollow portion independently conducts electricity.
