(57) [Summary] An operating temperature in the range of 125 ° C. to 135 ° C. satisfies the demand for environmental protection and reduces the fuse element diameter to approximately 30. Provided is an alloy-type temperature fuse which can be extremely thinned to about 0 μmφ, can suppress self-heating well, and can be operated accurately. In a temperature fuse using a low-melting-point fusible alloy as a fuse element, the alloy composition of the low-melting-point fusible alloy is Sn 33 to 43% by weight, In 0.5 to 10% by weight, The remainder is Bi. |
