PROBLEM TO BE SOLVED: To provide a bolt or a nut for an insert molding, moldable by integral molding without requiring a post process of processing an external shape, having rotation stopping force and slipping-out preventive force, capable of preventing erroneous insertion due to being insertable only in the correct direction, and superior in insertion performance in insertion. SOLUTION: This embedded body for the insert molding has a columnar or cylindrical insertion part 11 formed so as to be insertable at an optional angle in the peripheral direction into a molding metal mold for forming the insert molding in one end part, and has a projection part 12 having the rotation stopping function and the slipping-out preventive function formable by plastic processing in an outer peripheral part arranged in a position embedded in a synthetic resin material on the other end part side continuing into this insertion part.
