To provide a structure of electrode which facilitates connection between an electrode formed on a printed wiring board and an electrode of a microminiature vibrating motor.

The electrode of the microminiature vibrating motor is led out to an L-shaped electrode. The electrode of the printed wiring board and the L-shaped electrode are connected with each other through a conductive member comprising a coil spring. The microminiature vibrating motor is enclosed with a holder made of rubber. The holder has a hole into which the coil spring is inserted for connecting the electrode of the microminiature vibrating motor having the L-shaped electrode.
