PROBLEM TO BE SOLVED: To provide a removal method of an unneeded resin capable of precisely poking a desired position by a break pin reliably even if a molded lead frame is positioned easily. SOLUTION: The shape of an engagement section 2a at a pin side formed at the tip of the break pin 2 is set to a tapered projection, the tip of the projection is formed to be spherical, and the shape of an engagement section 7a at a resin side is set to a tapered recess, where the engagement section 7a is formed at the exposed section of a runner 7 and a gate 8 exposed by a first through hole 9A and a second one 9B formed on the molded lead frame 5.
