METHOD OF MANUFACTURING MAGNETIC ELEMENT AND MAGNETIC ELEMENT
First Claim
1. A method of manufacturing a magnetic element having:
- a first core member made from a resin material in which a magnetic powder is dispersed, and having an substantially plate-like base and a core part protruding from the approximate center of one face of the base;
a winding part formed as a tube by winding a conductive wire, which is placed on the base such that the core part is positioned within an inner periphery of the tube; and
,a second core member made from a resin material in which a magnetic powder has been dispersed, which is provided so as to surround a side of the first core member on which the core part is provided and the winding part,the method comprising at least;
a winding part placement step of placing the winding part on the face of the first core member on the side on which the core part is provided, such that the core part is positioned within the inner periphery of the winding part; and
an injection molding step of injection molding so as to surround the side of the first core member on which the core part is provided and the winding part with the resin material in which the magnetic powder has been dispersed,wherein, in the winding part placement step, the winding part is placed on the face of the first core member on the side on which the core part is provided, with at least a portion of an inner peripheral face of the winding part distanced from an outer peripheral face of the core part.

Abstract
The magnetic element has a first core member, a winding part, and a second core member, and is manufactured by way of at least a winding part placement step of placing the winding part on the face of the first core member on the side on which the core part is provided, such that the core part is positioned within the inner periphery of the winding part, and an injection molding step of injection molding so as to surround the first core member and the winding part with resin material, and in the winding part placement step, the winding part is placed on the face of the first core member on the side on which the core part is provided, with at least a portion of the inner peripheral face of the winding part distanced from the outer peripheral face of the core part.
