摘要： A method of producing a surface-mount inductor by encapsulating a coil with an encapsulation material containing a resin and a filler using a mold die assembly is provided. A tablet is prepared by preforming the encapsulation material into a shape having a flat plate-shaped portion and a pillar-shaped convex portion on a peripheral thereof A coil is a wound conductive wire having a cross-section of rectangular-shape. The coil is placed on the tablet to allow both ends of the coil to extend along an outer side surface of the pillar-shaped convex portion of the tablet. The coil and the encapsulation material are integrated together while clamping the both ends of the coil between an inner wall surface of the mold die assembly and the outer side surface of the pillar-shaped convex portion of the tablet, to form a molded body.

摘要： A surface-mount inductor according to this invention comprises a coil formed by winding a rectangular conductive wire in an outward spiral pattern (so that opposite ends of the conductive wire become outermost periphery), a core made primarily of magnetic powders and binder, and an external electrode formed on one surface of the core. Further, the surface-mount inductor is characterized by encapsulating the coil in the core so that winding axis of the coil is parallel to the surface of the core on which the external electrode is formed.

摘要： [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.
