徴とするサーキツトプロテクタ。 a thermal plate having a movable contact at one end and fixed to one fixed terminal at the other end; the other fixed terminal having a fixed contact to which the movable contact is pressed; and the fixed contact being biased by a return spring. A circuit protector comprising: an actuating punch that engages a movable contact that is in pressure contact with the movable contact and intervenes in a gap between the fixed contact and the movable contact that is caused by reversal of the thermal plate due to the flow of an overcurrent; The terminals are each integrally provided by insert molding, the thermally moving plate is engaged with one end of the one fixed terminal, and after the thermally moving plate is attached, a guide wall for inserting the return spring and the operating punch is provided. It is equipped with a base that is integrally formed, and a lid case that has a box-like external shape and is integrally protruded with a screw tube with a screw groove carved on the outer peripheral surface, which is fitted onto the base in a covering state. A circuit protector characterized by:
