       11 : An anti-seismic reinforced structure of a building wherein, in a structural frame comprising a pair of columns which are disposed to oppose each other to the right and left, an upper horizontal member and a lower horizontal member which are connected to each of the columns, a fiber reinforced cement siding according to  claim 1  being in contact with the structural frame in which a joint between the upper horizontal member or lower horizontal member and each of the columns or between these components are coupled with a metal fitting or a reinforcing metal, and the metal fitting or reinforcing metal is coupled in a position not interfering with the fiber reinforced cement siding with which it is in contact, or, counter bores are formed on the upper horizontal member or lower horizontal member and each column in the portions corresponding to the shape and thickness of the metal fitting or reinforcing metal so that the metal fitting or reinforcing metal does not interfere with the fiber reinforced cement siding, and the metal fitting or reinforcing metal is embedded and coupled in the counter bores, and 
 is fixed to the contact portion on the front surfaces of the upper horizontal member, the lower horizontal member and each of the columns at predetermined intervals of 30 mm or more but 200 mm or less with a nail or a screw.    
   
   
       12 : A fiber reinforced cement siding according to  claim 3 , wherein the value of resistance to moisture permeation of the painted portion is 2.67 m2·h·kPa/g to 6.67 m2·h·kPa/g.  
   
   
       13 : A fiber reinforced cement siding according to  claim 5 , wherein the value of resistance to moisture permeation of the painted portion is 2.67 m2·h·kPa/g to 6.67 m2·h·kPa/g.  
   
   
       14 : A fiber reinforced cement siding according to  claim 4 , wherein the value of resistance to moisture permeation of the first painted portion is 2.67 m2·h·kPa/g to 6.67 m2·h·kPa/g, and the value of resistance to moisture permeation of the second painted portion is lower than that of the first painted portion.
