NOVELTY - A plastic molding type secondary battery comprises a bare cell and a protective circuit board (30) connected to each other through a plastic molding for filling a space between them. The battery has trans-axial pinholes formed on a part made of the plastic molding in a direction parallel to the protective circuit board to come into contact with a surface of the protective circuit board proximal to the bare cell over a predetermined zone.    USE - As secondary battery.    ADVANTAGE - The invention prevents the problem of a protective circuit board being partially dislodged to generate a gap between the surface of an external input/output (I/O) terminal and a mold. It correctly orients a misaligned protective circuit board while eliminating factors responsible for poor quality of the battery due to the misalignment of the protective circuit board.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method of forming a plastic molding type secondary battery comprises mounting a bare cell and a protective circuit board in a mold (100); disposing supporting pins (310, 320) in the mold so that a lateral part of the supporting pin is in contact with a surface of the protective circuit board proximal to the bare cell such that the protective circuit board is disposed in a correct position; inserting an insertable core (210) to cause a front end of the insertable core to move through an axial opening (216) formed in the mold and contact a surface of an external input/output terminal formed on a surface of the protective circuit board distal to the bare cell while sealing the opening formed in the mold; and pouring a plastic resin into the mold.    DESCRIPTION OF DRAWING(S) - The figure shows a partial sectional view of the position of supporting pins taken through the narrowest side of the bare cell.
