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.

摘要： A method of producing a surface-mount inductor having an external electrode with high connection reliability even in a high-humidity environment is provided.The method comprises the steps of: forming a coil by winding an electrically-conductive wire having a self-bonding coating; forming a core portion using a sealant comprising metal magnetic powders and a resin so as to encapsulate the coil while allowing each of opposite ends of the coil to be at least partially exposed on a surface of the core portion; applying an electrically-conductive paste containing metal fine particles having a sintering temperature of 250° C. or less onto the surface of the core portion; and forming an underlying electrode on the surface of the core portion by sintering the metal fine particles through a heat treatment of the core portion to achieve electrical conduction with the coil.
