Abstract:
1. A plating device comprising: a plating solution bath capable of storing a plating solution and having a first electrode to be immersed in the stored plating solution; a treatment object holding mechanism configured to hold an object to be treated to bring a treatment surface of the object to be treated into contact with the plating solution; a contact disposed in said treatment object holding mechanism and brought into electrical contact with a peripheral edge of the object to be treated so as to make a conductive layer on the treatment surface, which is brought into contact with the plating solution, serve as a second electrode, said contact having a bellows construction movable in a direction facing the object to be treated and having a hollow portion; and a fluid supply mechanism configured to send into said hollow portion a fluid whose pressure is controlled, wherein said treatment object holding mechanism is capable of holding the object to be treated while said bellows construction of said contact is in a compressed state.
