The present invention is to provide a plate member which can improve material yield. The plate member forms a bus bar attached to a box main body of an electric junction box and includes a first terminal portion, a second terminal portion, and a connection coupling the first terminal portion to the second terminal portion. The plate member includes a first terminal portion equivalent corresponding to the first terminal portion, a second terminal portion equivalent corresponding to the second terminal portion, and arranged with a space against the first terminal portion equivalent along a longitudinal direction of a first terminal equivalent, and a connection equivalent corresponding to the connection. The connection equivalent couples the first terminal equivalent to the second terminal equivalent so that longitudinal directions of the first and second terminal equivalents are arranged parallel to each other.
