Patent ID: 7633372

Claim:
A chip type variable electronic part comprising: an insulating substrate with a through hole; an adjustment rotor formed of a metal plate in a bowl shape to receive a screwdriver and disposed on an upper surface of the insulating substrate; an internal terminal electrode plate made of a metal plate disposed in close contact with a lower surface of the insulating substrate; and a shaft portion integrally formed with the internal terminal electrode plate to be fitted in the through hole; the adjustment rotor including a bottom plate rotatably fitted to an upper end portion of the shaft portion, the upper end portion of the shaft portion being crimped to outwardly extend over an upper surface of the bottom plate, wherein the bottom plate of the adjustment rotor includes a portion that is fitted to the shaft portion, this portion being located at a lower level than an uppermost edge of an inner portion of the through hole on the upper surface of the insulating substrate, wherein the adjustment rotor is supported, at a bowl-shaped portion radially outward relative to the bottom plate, by the upper surface of the insulating substrate, and wherein a plate thickness of a portion of the internal terminal electrode plate around the shaft portion is partially reduced, and a film that covers an inner portion of the hollow shaft portion is adhered to a lower surface of the portion with the reduced thickness.
