Zusammenfassung:	The present invention provides a composite molded resin body without complicating the manufacturing step, excellent in at least one of adhesion or air tightness between different materials of a metal and a resin and, as a result, capable of providing an inexpensive composite molded resin body. Crater-like intricate indents formed by melting and scattering of a metal surface are provided by irradiating with high density energy such as a laser beam or an electron beam the surface of the metal member. By using the irradiation condition that the crater-like indents have partially overlapped regions, gangue-like prominent portions formed by melting and scattering of the metal surface, a spherical metal splash formed at the top end of the prominent portions, and a roughed surface shape where particulate sputtering formed upon fabrication is secured. Thus, the molded resin intrudes into the constricted space formed by surface roughening to provide an anchoring effect against volume change of the resin in the directi
