Summary:The present invention provides a protection circuit module (PCM) insert injection mold, and a battery having the same. The PCM insert injection mold is made by inserting a PCM, including a plate having protection circuit formed thereon and connection terminals and optionally leads, with the protection circuit plate, connection terminals and leads being electrically connected, into an inner space of a mold, and injecting a molten resin into the inner space of the mold such that the leads are partially exposed to the outside where the PCM includes the leads, or such that the connection terminals are partially exposed to the outside where the PCM does not include the leads. Since the PCM is prepared by insert injection molding under the condition that the protection circuit and battery cell are not connected, i.e., that power is not applied to a battery, the PCM can be molded using general resins, is electrically stable, does not require a coating step for preventing short circuit, and is rare electrically damaged.
