To provide a bicolored safety pin having a body whose inside and outside are colored differently.

This bicolored safety pin has a body 1 whose inside portion 1a and outside portion 1b are colored differently, the inside portion 1a of the bicolored safety pin is made of a synthetic resin of a certain color and molded to be attached with a support part 3 of a pin root 2a and the outside portion 1b is made of a synthetic resin of another color and molded to be attached with a locking part 4 of a pin tip 2b. This constitution improves a decorative value, and when being put on clothes, functions as an accessory to set it off. On the back of the body, a support part of the pin root and the locking part of the pin tip are formed of different colors to allow a user to easily discriminate the pin root from the pin tip and facilitate the attachment/detachment of the safety pin.
