To surely, preferentially fuse one fuse element portion to the other fuse element portion in a temperature fuse with resistor having both side membrane electrodes a, b and an intermediate membrane electrode on one surface of a substrate, arranging a fuse element over these membrane electrodes, having a fuse element portion m between the membrane electrode a and the intermediate electrode and a fuse element portion n between the membrane electrode b and the intermediate membrane electrode, and having a membrane resistor fusing the fuse element portions n, m by heat generated by turning on electricity on the other surface of the substrate.

Distance between the fuse element portion n and the membrane resistor r differs from distance between the fuse element portion m and the membrane resistor r.
