Wire-wound coil and method for manufacturing the same

摘要

A wire-wound coil includes a core, electrodes, and a wire. The core includes a winding core for winding the wire and a pair of flanges. A depression is formed on the inner lower portion of each of the flanges. The depression has a curved surface that curves inward in a direction from the inner wall to the outer wall of the flange and smoothly connects with the peripheral wall of the winding core. The end portions of the wire are extended along the curved surfaces and the tips of the end portions are bonded to the electrodes. The end portions are in an unstressed state and prevent the generation of tension caused by the contraction of a coating agent.
