Metal-resin composite and method and apparatus for manufacturing the same

A metal-resin composite comprising:

• a metal plate including a plurality of cut-and-raised portions, each of the plurality of cut-and-raised portions including a cutout hole and a cut-and-raised piece, the cut-and-raised piece being raised from an edge of the cutout hole, so that a plurality of cutout holes are formed in the metal plate;
• and
• one resin material disposed only on one surface side of the metal plate but not disposed on a lower surface of the metal plate, the resin material cured by burying all of the plurality of cut-and-raised portions, the resin material integrated with the metal plate, wherein
• the cut-and-raised piece of each of the plurality of cut-and-raised portions is cut-and-raised only on the one surface of the metal plate,
• the lower surface of the metal plate is flat, and
• the one resin material covers only a portion on the one surface side of the metal plate.
