1. A surface mount inductor comprising:
a molded body made of a composite material containing magnetic powder; and
a metal plate including a first metal plate portion embedded in the molded body and a second metal plate portion extending from the first metal plate portion to an outside of the molded body,
wherein
the second metal plate portion is extended from a side surface or mounting surface side of the molded body, is arranged along the molded body with a bent portion, and forms an external terminal arranged at least on the mounting surface side of the molded body,
the external terminal includes a plating layer on a surface on an opposite side from a surface facing the molded body, and does not include any plating layer on the entire surface facing the molded body,
the first metal plate portion constitutes a coil conductor, and
the plating layer is provided on both the coil conductor and the external terminal.
