ABSTRACT:
A surface mount inductor has a drum core, a winding to be wound around a winding shaft section of the drum core, a case body of a nonconductive material to be disposed to surround the winding, a binding terminal fixed to the case body and protruding radially outward from the case body to be bound a winding terminal to, and a metal terminal member having a planar terminal to be a contact portion with a substrate when the surface mount inductor is surface mounted on the substrate. The inductor includes an extended portion protruding radially outward from the case body and having a wider width than or approximately the same width as of the binding terminal, the extended portion being disposed at a overlapping position with the binding terminal in a height direction of the drum core. The winding terminal is wound around from the outer peripheral side of both the binding terminal and the extended portion.
