The present invention is to provide a resin-forming mold having high releasability and permitting a production without increasing production costs. The resin-forming mold can be used to produce a resin-molded product having minute uneven portions on a front face thereof, such as a surface light source device-use light guide for a liquid crystal display, an aspherical micro-lens, micro-Fresnel lens and an optical disk. In the stamper (resin-forming mold) 10 provided with an electroformed layer 11 and a conductive film 12 formed on the electroformed layer 11 , the front face layer 12 c of the conductive film 12 is formed of aluminum and a back face 12 d is formed of nickel as an electroconductive metal. In addition, the constituent composition of the aluminum and the nickel continuously changes from the front face 12 c toward the back face 12 d. The front face 12 c may be formed of aluminum and oxygen. The aluminum may combine with the oxygen to form an oxide of aluminum.
