A chip type variable electronic part includes an insulating substrate with a through hole, an adjustment rotor formed of a metal plate in a bowl shape and disposed on the upper surface of the insulating substrate, an internal terminal electrode plate made of a metal plate disposed in close contact with the lower surface of the insulating substrate, and a hollow shaft integrally formed with the internal terminal electrode plate to be fitted in the through hole. The adjustment rotor has a bottom plate rotatably fitted to an upper end portion of the hollow shaft so that the bottom plate makes close contact with the surface of the insulating substrate. The upper end portion of the hollow shaft is crimped to outwardly extend. The bottom plate of the adjustment rotor is smaller in thickness than the remaining portions. Thus, the overall height is reduced without reducing the insertion depth of a screwdriver into the rotor, and without degrading the strength of the insulating substrate.
