A metal resin composite-molded article which can suppress deformation induced by laser processing in a technique for improving the adhesion between a metal plate and a resin by forming grooves on the surface of the metal plate by means of a laser, even if the metal plate is thin. A metal resin composite-molded article obtained by insert-molding a resin composition on a metal plate having a thickness of 500 &#x3bc;m or less, grooves are formed on the surface of the metal plate in which the resin composition is inserted, the width of the grooves is 30-300 &#x3bc;m, the depth of the grooves is at most 24% of the thickness of the metal plate, and the ratio of the width to the depth is 0.1-2.5.

Metal resin composite-molded article and method for manufacturing same

A polyacetal resin composition makes it possible, when formed into a molded article, to minimize deterioration during contact with sulfur-containing fuel or an acidic detergent. The polyacetal resin composition contains (A) 100 parts by weight of polyacetal resin, (B) 0.1-1.0 parts by weight of hindered phenolic antioxidant, (C) 0.1-2.0 parts by weight of alkaline earth metal oxide, (D) 0.5-3.0 parts by weight of polyalkylene glycol, and (E) 0.01-1.0 parts by weight of polyvalent fatty acid full ester. This polyacetal resin composition minimizes reductions in the weight of a molded article even after the molded article has been immersed in sulfur-containing fuel.
