The main plated portions are arranged next to one another. One of the two main plated portions located at two ends in a direction in which the main plated portions are arranged includes an edge at a portion located at a side of the main plated portion that is far from an adjacent one of the main plated portions. The auxiliary plated portion is located farther from the adjacent main plated portion than the main plated portion including the edge and spaced apart from that main plated portion. The metal film on the auxiliary plated portion is located at a section of the auxiliary plated portion that is non-visible when the product is viewed from the front.
