Abstract: Process for producing a surface-mount inductor. A forming die assembly comprises a lower die, a first upper die having three peripheral side surfaces and one opening, and a second upper die for closing the first upper die opening, thereby defining a cavity therein. The coil is formed by winding a wire and processing its led-out end such that it contacts with a side surface of the first and second upper dies. The coil is placed in the cavity from the open side of the first upper die such that its led-out end contacts with a side surface of the first and second upper dies. The coil is sealed with a sealant containing a magnetic powder while the first and second upper dies are clamped together, to form the core. An external electrode is formed on the core and the led-out end of the coil is connected to the external electrode.
