ABSTRACT:
A chip-type component11includes an insulating chip substrate12whose upper surface is provided with a resistor element13and a cover coat14covering the resister film. At the opposite ends of the substrate, terminal electrode films15, 16are formed for the resistor element in a manner such that they extend onto the lower surface12aof the insulating substrate. The lower surface12aof the substrate is provided with an insulating projection18between the terminal electrode films, where the projection includes a peak portion18apositioned at or near the center of the insulating substrate in a longitudinal direction along which the terminal electrode films are spaced from each other. This prevents the insulating substrate from breaking when the chip-type component11is vacuum-sucked by a collet nozzle19to be supplied to a printed circuit board17.
