Document Type and Number:
Japanese Patent JP5877296
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a coil component which improves reliability by preventing the generation of a crack on a magnetic core or a terminal, and a manufacturing method of the coil component.SOLUTION: A coil component includes: a magnetic core 21; a coil portion 22 embedded inside the magnetic core 21; and a terminal 24 projecting a lead wire 23 of the coil portion 22 from the magnetic core 21 and folding that from a side surface toward a bottom surface. The terminal 24 is composed of: a platy base portion 26, which is from the inside of the magnetic core 21 to a part including an R potion formed by being folded to a lower surface direction of the magnetic core 21; and a platy terminal portion 27 continuously contacting with the base portion 26, and folded from the side surface to a bottom surface of the magnetic core 21. A recessed portion 28 uniformly depressed from the surface of the terminal portion 27 is formed on a surface of the base portion 26, and the length in an extending direction of the lead wire 23 of the recessed portion 28 is formed to be larger than the thickness dimensions of the base portion 26, thereby forming the base portion 26 in a plate shape thinner than the terminal portion 27.
