1. A heat dissipating structure having a plurality of heat dissipating members connected for enhancing heat dissipation from a heat source, wherein each of the heat dissipating members comprises:
a heat conduction sheet in a spirally winding shape for conducting heat from the heat source,
a cushion member provided on an annular back side of the heat conduction sheet, the cushion member being deformable following a surface shape of the heat source more easily than the heat conduction sheet,
an adhesive layer for fixing the heat conduction sheet and the cushion member to each other, the adhesive layer being more elastically deformable than the heat conduction sheet, and
a through passage penetrating in a winding direction of the heat conduction sheet,
wherein the heat dissipating members orthogonally arranged to the winding direction of the heat conduction sheet are connected by a connection member, wherein the adhesive layer is a multi-layer formed by applying a pressure-sensitive adhesive to both surfaces of a resin layer.
