Abstract
In an inductance component, a stress is not locally applied even in the condition where heat is applied to entire component, such as when implementing soldering, so that high reliability is realized. For realizing this, the component includes an element, a coil formed in the element, terminals electrically connected to the coil, and magnetic layers arranged so as to be substantially parallel to a winding surface of the coil are formed in the element and the entirety of the magnetic layers is covered with a material of which thermal expansion and contraction rate is uniform.
