  • Publication number: 20150371766
    Abstract: A coil component is provided with first wire and second wires that are wound around a winding core. nth turns of the first and second wires are wound around a surface of the winding core in this order in parallel and form a first winding layer. Each of n+1th and subsequent turns of the second wire is wound around the surface of the winding core so as to be parallel to a previous turn of the second wire and form the first winding layer. Each of n+1th and subsequent turns of the first wire is wound on the first winding layer so as to be fitted into a valley of the first winding layer formed by the same and previous turns of the second wire and form a second winding layer. The same turns of the first and second wires are adjacent to each other at each turn.
