A composite shaped article with uneven configuration junction face, comprising a resin member and a plate member composed of topside and underside arranged surface layer base materials integrated with a core layer base material interposed therebetween, the plate member and the resin member joined together with an uneven configuration at the side end faces facing each other. In the composite shaped article, the length of actual junction line formed along the unevenness of the uneven configuration is 1.05 mm or greater per mm of a protrusion passage line consisting of a continuity of line segment linking neighboring protrusion tops with each other in the uneven configuration drawn by the surface layer base materials.
