Abstract
A Positive Temperature Coefficient (PTC) device, a Protective Circuit Module (PCM) including the PTC device, and a secondary battery including the Protective Circuit Module (PCM) are provided. A support portion is formed at one end of a conductive plate of the PTC device, a conductive layer disposed on the upper portion of the PTC main body is fixed to the Protective Circuit Module (PCM), and the support portion is fixed by a coated adhesive that is melted at a high temperature and then hardens when the high temperature is removed, thereby preventing the PTC device from swaying or twisting.
