A forming mold, forming mold manufacturing method, injection molding device and molded article manufacturing method are provided which enable reproducing a fine texture pattern while excellently maintaining the surface quality of the molded article. A cavity mold (20), which is a forming mold, comprises a mold body (21), and a plating layer (26) provided on the surface of the forming surface (22).In this case, the forming surface (22) has a texture transfer surface (23) for forming a texture pattern, and the texture transfer surface (23) is provided with first peaks and valleys (24), and second peaks and valleys (25) which are formed in the surface of said first peaks and valleys (24) and which have a peak-and-valley width less than that of the first peaks and valleys (24); the width of these peaks and valleys is within the range from 10 mu m to less than 500 mu m. Further, the plating layer (26) is an electroless plating layer, and the thickness in at least one region of said platinglayer (26) is in the rang
