The tray part is formed as a separate body from the attachment part. The heater guide is made of metal and comes into contact with the heater and the tray part. The heater guide is attached to the attachment part to hold the heater, and transmits heat of the heater to the tray part.

1 . An ice-making tray comprising:
 an attachment part;   a metal tray part formed separately from the attachment part;   a heater configured to heat the tray part; and   at least one heater guide made of metal which is in contact with the heater and the tray part, the heater guide being attached to the attachment part to hold the heater, and configured to transmit heat of the heater to the tray part.   
     
     
         2 . The ice-making tray according to  claim 1 , wherein the heater guide includes a raised portion which is in contact with the tray part. 
     
     
         3 . The ice-making tray according to  claim 1 , wherein the heater guide includes a fin extending towards a side opposite to the tray part. 
     
     
         4 . The ice-making tray according to  claim 1 , wherein the ice-making tray includes a plurality of heater guides, and the plurality of heater guides are arranged at positions equally dividing the tray part in an axial direction extending along the heater. 
     
     
         5 . The ice-making tray according to  claim 1 , wherein
 the ice-making tray includes a first heater guide arranged at a basal side of the heater and a second heater guide arranged at a distal side of the heater, and   a length of the first heater guide in an axial direction extending along the heater is larger than a length of the second heater guide in the axial direction.   
     
     
         6 . The ice-making tray according to  claim 1 , wherein a portion of the heater guide contacting the heater has a circular arc shape so as to lie along a shape of the heater.
