A partial plating method capable of applying fine hard gold plating, a laser plating device capable of applying partial plating to a minute region with high positional precision, and a plated member. The partial plating method comprising plating a region to be plated by projecting a laser beam having a wavelength of 330 nm or more and 450 nm or less. A laser plating device comprises a plating tank, a laser oscillator for emitting a laser beam, a conveying device for conveying a member to be plated, a photoelectronic sensor for detecting the position of a positioning hole of the member to be plated, and a galvanometer scanner having a galvanometer mirror capable of scanning the laser beam. The plated member is applied with fine spot plating by the laser plating device.
