Abstract A synthetic resin part integrally formed with metal members manufactured by the steps of below. A contact set where contacts provided with a number of embedded pieces, are integrated through a bridge is formed in manufacturing a lamp body for a vanity mirror. Then, this contact set is inserted in a mold for forming a body, and an intermediate body where the body is integrated with the contact set is formed by injecting the resin for the body. The bridges connecting the contacts are cut at a punching hole by punching punched holes to complete the lamp body with the respective contacts being electrically independent. With this manufacturing method, the assembling accuracy of the synthetic resin part to metal members is enhanced, there is no danger of unnecessary contact between metal members, and the time for assembling metal members is saved to contribute to cost reduction.
