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.
