Claim:
1. A fastening structure for a resin-foam core composite plate, in which the resin-foam core composite plate is stacked by sandwiching a core of a resin foam between metal plates and is fastened to a counterpart member, wherein: a fastening part of the resin-foam core composite plate includes a through-hole and a compression periphery part at which the core of the resin foam is compressed around the through-hole; and a metallic fastening member inserted into the through-hole is coupled to the compression periphery part by crimping or welding, so that the fastening member is fastened to the counterpart member, wherein: the fastening member has a pedestal-attached cylindrical shape in which a pedestal part thereof is provided at one end side of a cylindrical part thereof; the compression periphery part includes a tubular wall part standing from a periphery of the through-hole; and the cylindrical part of the fastening member is inserted into the through-hole from a proximal end side of the wall part, pressing the pedestal part against the compression periphery part, and the fastening member is crimped to a distal end side of the wall part so as to forcibly spread a distal end side of the cylindrical part protruding from the distal end side of the wall part.
