PROBLEM TO BE SOLVED: To provide a heat dissipation structure capable of suppressing reduction of heat dissipation efficiency caused by aging, by preventing fin pitch distortion and improving adhesion between a fin and a heater.SOLUTION: A heat dissipation structure comprises: a plurality of pairs of heat dissipating fins in each of which a notched part including a portion similar to an outer edge shape of a cross section orthogonal to an axial line of a stick-like heating element is provided in one end of a plate part, and each of which is formed from an elastic plate body; a protrusion which is erected substantially vertically to the plate part along an edge of the notched part and has an inner edge shape similar to the notched part; and a pair of fin supports mounted to the heating element for supporting the plurality of pairs of heat dissipation fins. Inner edges of the notched part and the protrusion of the heat dissipation fin are abutted to the heating element. The paired heat dissipation fins are disposed symmetrically with respect to the axial line of the heating element and alternately along an axial line direction of the heating element. Distal ends of the protrusions of the neighboring heat dissipation fins are abutted at other end sides of the heat dissipation fins. The pair of fin supports hold the heat dissipation fins while elastically deforming them. |
