A molding method includes: setting a bus bar at a first mold main body portion of a fixed mold by supporting a terminal base of a tuning-fork terminal with a terminal base receiving portion of the fixed mold in a state where the tuning-fork terminal is protruded outside a cavity formed by the first mold main body portion of the fixed mold and a second mold main body portion of a movable mold being joined together; joining the movable mold together with the fixed mold by abutting an abut step portion of the movable mold to a receiving abut step portion of the fixed mold and nipping the terminal base of the tuning-fork terminal with the terminal base receiving portion and a terminal base abut portion of the movable mold; and injecting resin into the cavity in the nipped state.
