ABSTRACT:
A wire wound electronic part includes a core having a wire wound core and flanges formed on both ends thereof, a coil conductor wound around the wire wound core and terminal electrodes disposed at the bottom of the flange, in which both ends of the coil conductor are conductively connected to the terminal electrodes by a solder, wherein a pair of grooves are formed at the bottom crossing the wire wound core of one of the flanges. The groove has a bottom and side walls disposed being slanted on both sides thereof, in which the vertical height for the side wall is formed larger than the length for the bottom of the side wall. The terminal electrodes are contained in the groove, and edge portion in the lateral direction of the terminal electrode is restricted by the side wall of the groove. The edge portion in the lateral direction of the terminal electrode is restricted by the side wall of the groove, which makes the lateral size stable and suppresses the movement of the molten solder in the lateral direction of the groove, thereby preventing unstable height and attitude of the wire wound electronic part upon mounting to a circuit substrate.
