PROBLEM TO BE SOLVED: To provide an oscillatory driver using a hardening film making use of the property of an electroless plated film, for the contact face of a contactor, at low cost and with good mass-productivity. SOLUTION: In an oscillatory driver which drives an oscillator 2 for exciting vibration and a contactor 7 to contact with this oscillator relatively through friction, one sliding face between the oscillator 2 and the contactor 7 is processed for leveling, and then electroless plating is applied to make a hardening film, and the other sliding face is made of a composite resin layer 6 containing the reinforcing material in resin or a resin composition. |
