Abstract:
1. An inductance component comprising: an element including a material having a uniform thermal expansion and contraction rate; a coil disposed in said element, and wound in a winding surface; a terminal electrically connected to said coil; and a magnetic layer disposed in said element, said magnetic layer being arranged substantially in parallel to said winding surface of said coil, wherein said magnetic layer is entirely covered with said element, such that said magnetic layer contacts and is entirely covered with said material having a uniform thermal expansion and contraction rate, wherein a slit is formed on said magnetic layer, and said slit is filled with a portion of said element, and wherein said slit is substantially in a V-shape, and said slit is one of a plurality of slits spread in parallel to one another from a bending portion of said substantially V-shape in an outer peripheral direction of said magnetic layer.
