PROBLEM TO BE SOLVED: To reduce the area of a circuit board, to increase the packaging density, to facilitate electrical connection between a dive circuit for driving a vibration generator and the vibration generator even if the vibration generator itself is downsized, and to increase productivity of portable radios, wristwatches or the like. SOLUTION: In the apparatus for electrical connection between a vibration generator 1 and a printed wiring board 12, the vibration generator 1 is covered with a holder 2 and an electrode 4 installed on the vibration generator 1 through a conductive coil spring 10 provided an the holder 2, and an electrode installed in a specified position of the printed wiring board 12 are electrically connected to each other while the face housing 13 and the back housing 14 are integrated.
