In a chip type variable electronic part including an insulating substrate, and an adjustment rotor made of a metal plate rotatably mounted on an upper surface of the insulating substrate, in which the rotor is constituted of a first plate formed in a bowl shape to receive a screwdriver that rotates the rotor, and a second plate superposed on an upper surface of the first plate and integrally coupled thereto via a fold-back joint, and the second plate includes a screwdriver engagement hole perforated therein for the screwdriver to be fitted in, the fold-back joint is bent downward from an upper surface of the second plate, thereby preventing deformation of the fold-back joint when the rotor is rotated with the screwdriver.

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.

To provide a decorative component, a timepiece, and a manufacturing method of the timepiece capable of improving workability for color development and of enhancing decorativeness. A surface of an oscillating weight 160 develops a color by forming anode oxide films 22a and 22b on the surface of the oscillating weight body 164 which is formed using titanium or a titanium alloy, and on the surface of the oscillating weight body 164, of the portions at which the anode oxide films 22a and 22b are formed, a nitridization treatment layer 21 is formed at the portion at which the anode oxide film 22a is formed.

A part, a timepiece, and a manufacturing method of the part capable of avoiding the limitations on the member which is used, expanding variation in the design, being easily manufactured, and improving the aesthetic appearance are provided. In an oscillating weight in which a body of the oscillating weight to which anodizing can be applied and a conductive weight are fixed to each other, an insulating layer is interposed between the body of the oscillating weight and the weight.

A bottom plate of the adjustment rotor is rotatably fitted to the upper end portion of the shaft portion, and the upper end portion of the shaft portion is crimped to outwardly extend over the upper surface of the bottom plate. A portion of the bottom plate of the adjustment rotor, fitted over the shaft portion, is located at a lower level than the uppermost edge of an inner portion of the through hole on the upper surface of the insulating substrate. Thus, the overall height of the chip type variable electronic-part is reduced with an increased insertion depth of a screwdriver into the rotor.
