A first mold 2 for forming a first covering 11 on the minus side of a synthetic resin molded product (for example, a toilet seat in a Western-style toilet) and a second covering on the other side of the synthetic resin molded product are arranged. A heating element 10 is provided, which is made up of a second metal 573 and covered with the first coating 11 and the second coating 12, and one side of the synthetic resin molded product is placed in the first mold 2. A first groove 5 is formed in which the fluid synthetic resin 4 to be formed flows, and the second mold 3
a second mold (2) disposed opposite to the first groove 5 of the first mold 2;
A second mold member 12 having a groove 6 formed thereon and a heating element protruding into the first groove 5 of the first mold 2 and having a fluid synthetic resin 4 disposed in the second groove 6; 1 of 10: A flow port 8 is formed for flowing from the side.1. There is.
