Abstract: [Technical Problem]This invention provides a surface-mount inductor that is capable of positioning a coil in a predetermined position in a mold, thereby to position the coil in a predetermined position of a core and to prevent led-out ends from being buried in the core.[Solution to the Problem]A surface-mount inductor of the present invention comprises: a coil formed by winding a winding wire; and a core containing a magnetic powder and including the coil therein. The coil has opposite led-out ends, each of which is exposed on respective ones of opposed side surfaces of the core. Each of the led-out ends of the coil is connected to an external electrode formed on the core.

Abstract: A method of producing a surface-mount inductor including an external electrode having high fixing strength with respect to an element body even in a high-humidity environment. The method includes the steps of: winding an electrically-conductive wire to form a coil; forming a core using a sealant primarily containing a metal magnetic powder and a resin in such a manner as to encapsulate the coil in the sealant while allowing each of opposite ends of the coil to be at least partially exposed on a surface of the core; reducing smoothness of a surface of at least a part of a portion of the core on which an external electrode is formed as compared to a surface therearound; and forming the external electrode on the core in such a manner as to be electrically conducted with the coil.
