PROBLEM TO BE SOLVED: To provide a power supply which enables the shape of a thin winding body to be maintained with sufficient reproducibility, and is equipped with magnetic components in which the reliability and characteristics are improved, while responding to miniaturization and reduction in thickness, by using a magnetic core in which manufacturing yield is improved after resin coating. SOLUTION: The power supply is provided with the magnetic components which are made by applying windings to a thin magnetic core, which has a winding body 1 formed by winding a soft magnetic alloy thin band 2 with a width of 5 mm or smaller in a toroidal shape, and a resin coating layer which is formed by coating in a periphery side of the winding body 1. In the inside-diameter side end of the winding body 1, a terminal welding 5 is subjected over the soft magnetism alloy thin band extending over a plurality of layers. COPYRIGHT: (C)2007,JPO&INPIT
