A PTC thermistor includes two electric conducting plates connected with different electrodes and an intermediate insulating plate clamped between the two electric conducting plates. The intermediate insulating plate has its surface bored with openings at locations respectively corresponding with those of each PTC thermal resistance member for the PTC thermal resistance member to be engaged therein. The intermediate insulating plate can surely separate and insulate the two different-electrode electric conducting plates and stably fix the PTC thermal resistance members in position.
