Abstract: A heat dissipation structure for a battery includes a plurality of heat dissipation members. The heat dissipation members are each provided with: a heat conductive sheet having a shape that extends while winding in a spiral shape for transferring the heat from the heat source, a cushion member which is provided on an annular rear surface of the heat conductive sheet and can be more easily deformed to conform to the outer surface shape of the heat source than the heat conductive sheet, and a penetration path penetrating in the direction in which the heat conductive sheet extends while winding. The plurality of heat dissipation members is connected to each other by connection members in a state of being aligned in a direction perpendicular to the direction in which the beat conductive sheet extends while winding.

Abstract: A member for a push-button switch has key top members positioned close to each other through a distance of 1.5 mm or shorter at low cost and with high yield. The member has multiple key top members having resin key top cores and thermoplastic films covering the key top cores other than the lower surfaces thereof. The key top members are formed so that an interval between at least one set of adjacent key top members is 1.5 mm or shorter. In the key top members adjacent to each other through a distance of 1.5 mm or shorter, the maximum thickness of the thermoplastic films covering the key top cores is within the range of 75 to 350 ?, and the ratio of the minimum thickness of the thermoplastic films covering the key top cores to the maximum thickness is within the range of 0.4 to 0.9.
