Claims

[Scope of utility model registration request]

A fusible alloy is fixed between the ends of a pair of lead wires, the fusible alloy portion is housed in an insulating cylinder, and a sealing resin is used to seal between the openings at both ends of the insulating cylinder and the lead wires. The temperature fuse is characterized in that the portion of the lead wire accommodated in the insulating cylinder is provided with a large part with an outer diameter slightly smaller than the inner diameter of the insulating cylinder, and a small diameter part is provided at the tip. temperature fuse.
