Abstract
A surface mounted inductor is equipped with a coil formed by winding a conductive wire, and a formed body in which the coil is sealed with a sealing material that mainly contains metal magnetic powder and a resin. The coil is embedded so that surfaces of lead-out ends are exposed on surfaces of the formed body. The resin at portions of surfaces of the formed body where external terminals are formed is removed, and the metal magnetic powder and a plating layer forming the external terminals are joined to each other, thereby connecting the external terminals and the lead-out ends of the coil.
Claims2
A surface mounted inductor comprising:
- a body including metal magnetic powder and a resin,
- a coil configured by a wound conductive wire and having lead-out ends, the coil being embedded in the body, and
- external terminals, wherein,
- surfaces of the body include a first portion where the resin existing in the surfaces of the body is selectively removed according to a shape of the external terminal, and
- a second portion where the resin existing in the surfaces of the body remains,
- in the first portion, the metal magnetic powder exposed on the surfaces of the body and a plating layer configuring the external terminals are joined to each other, and
- the external terminals and the lead-out ends of the coil are connected to each other.
