Abstract
The present invention minimizes the deviations of desired fuse time in the resistors with fuse function, and this is made of a resistor layer 21 consisting of fine electro-conductive particles, fine glass particles having a melting temperature higher than the forming temperature of the fine electro-conductive particles, a solvent dispersing these particles uniformly, and metal caps 23 connecting resistor film 21 at the ends of substrate 22.
