PROBLEM TO BE SOLVED: To provide a thermal fuse with a current fuse function making a heat-sensitive fuse element operate by a current value of a heating element, of which, heating resistance is easily and accurately adjusted by a processing treatment. SOLUTION: The thermal fuse with the current fuse function 10 comprises a fuse element 19 made of a low-melting-point fusible alloy with a flux film 17, laid between electrode parts 11, 12 of lead members 15, 16, a heating means 30 formed at least at one of the guiding parts 13, 14 of the lead members15, 16, and an air-tight package 20 airtightly sealing the fuse element. The heating means 30 is set at a prescribed resistance value by an easily adjustable processing treatment such as forming a window hole 31 by punching, or forming a notch 32 by laser trimming.
