Abstract
There is provided a polymer PTC device including a polymer PTC element having a lower resistance. The production process of a PTC device which includes a PTC element (102) having a polymer PTC component (110) and metal electrodes (104) placed on both sides thereto; and a lead (106) connected electrically to at least one of the metal electrodes, is characterized in that the polymer PTC component is formed of an electrically conductive polymer composition which comprises a polymer material and conductive fillers dispersed therein, and the connection of the lead to the metal electrode is performed at a temperature which is lower than the melting point of the polymer material.
