A stable bonding processing for metal, of which at least a part is plated, is provided. A plated metal bonding apparatus performs bonding of a first metal and a second metal. At least one from among the first metal and the second metal has a plated bonding portion where the bonding processing is to be performed. A bonding processing unit performs bonding of the first metal and the second metal using sound vibration and/or ultrasound vibration. The bonding processing unit performs the bonding processing using a plated material or otherwise using a metal portion in a state in which a plating material has been removed.
