<P>PROBLEM TO BE SOLVED: To effectively radiate heat of a heating element, and also suppress a deviation of a position and an attitude of the heating element. <P>SOLUTION: A heat radiation structure of the heating element body is formed of the heating element body having a heating element 13 which generates heat with the drive, and a first plate-like member 31 and a second plate-like member 51 made from a metal joined so as to be stacked on one face of the heating element body. The first plate-like member has a notch part 33 opened by penetrating therethrough and is joined to the heating element body so as to close the notch part, and the second plate-like member has a protrusion part 53 fitted to the notch part of the first plate-like member and configured so as to be joined to the heating element body through the notch part. A modulus of longitudinal elasticity of a material composing the first plate-like member is made larger than a modulus of longitudinal elasticity of a material composing the second plate-like member. <P>COPYRIGHT: (C)2012,JPO&INPIT |
