゛ A temperature-sensing section made of a shape-memory alloy that has the characteristic of rapidly changing its outer shape when it reaches a predetermined temperature, an accommodation plate for detecting external temperature provided close to the temperature-sensing section, and ``the shape-memory device. It is composed of a spring member that supports the alloy, an electric contact that moves according to the deflection of the shape memory alloy, and a fixed contact for the electric contact, and generates heat by self-heating by energizing the temperature sensing part and by heat conduction of the accommodation plate. A temperature-sensitive circuit protector, characterized in that the contacts are opened and closed based on changes in the external shape of the temperature-sensing section.
