To provide a fuse with a substrate type resistor which can reduce a planar dimension and can improve heat transference from the outside to the fuse (a fusible metal piece).

The fuse with a resistor has the resistor 2 and the fusible metal piece 4 fused with heat generation by conduction of the resistor 2. The resistor 2 is embedded in an insulating substrate 1. Electrodes 32-34 for mounting a fusible metal piece are provided to one face of the insulating substrate in which the resistor is embedded. The fusible metal piece 4 is connected to the electrodes 32-34. The resistor 2 in the insulating substrate 1 is electrically conducted to the electrode 34 for mounting a fusible metal piece through a hole h1 of the insulating substrate 1.
