A method of producing a molded product includes preparing a mold for insert molding, setting an insert member, forming a cavity in a condition in which the insert member is disposed by closing the mold and injecting a molten resin into the cavity. The mold for insert molding includes first and second molds, and the first mold has a guide surface provided at a part corresponding to a trunk portion of the molded product within a wall surface defining a groove portion which constitutes a part of the cavity. The insert member is set at the groove portion of the first mold while the projecting portion being guided by the guide surface.
