PURPOSE: To provide a chip resistor with fuse function in which the fusing time is shortened and minimized in dispersion by providing an electrically opened part on a resistor pattern printed and baked on an insulating base, and short-circuiting the opened part with a conductive metal having fuse function such as Pb, Al or the like.

CONSTITUTION: A thick film electrode 3 is printed and baked on an insulating base 1, and a resistor 2 is then printed and baked thereon. An electric opened part 4 is partially provided on the resistor pattern, and a conductive metal thick film 5 is printed and baked in a band form on the opened part, and short- circuited. As the thick film material to be short-circuited, Pb, Sn, Zn, Al, Cu, Fe and alloys thereof can be used. A preliminarily grooved base is used, and the thick film material to be short-circuited is arranged thereon to pass above it, whereby dispersion of fusing time can be suppressed. The resistor film from which the short-circuited position is removed is trimmed, whereby the resistance value can be precisely regulated.
