PROBLEM TO BE SOLVED: To provide a mold capable of simply demolding a molded product by one operation and beautifully finishing the molded product, a synthetic resin product manufacturing method using it and a synthetic resin product obtained by the synthetic resin product manufacturing method. SOLUTION: The mold has a foundation part 20 having a root part 23 attached to a base plate and both side surfaces extending to a leading end and tapered to approach each other toward the leading end, and a pair of two split shaping parts 21 and 22 attached to and capable of advancing and retreating along two side faces of the foundation part 20 and having a female-screw-shaping part 31 formed to the leading end part thereof. The two divided shaping parts 21 and 22 advance along the two tapered side faces of the foundation part 20 after molding to approach each other to unscrew the female-screw shaping part from a female screw part of the molded product.
