Title:
ELECTRONIC COMPONENT AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2007109935
Kind Code:
A
Abstract:

To solve the problem wherein a conventional electronic component has limitation in decreasing its height because a substrate is used as its constituent.

A three-dimensional stereoscopic coil pattern is formed of internal electrodes 108 through vias in the inside of a resin used as a protective portion without using a substrate. With this configuration, its low height is provided, the resin used as the protective portion is made of a first colored resin 102 or a second colored resin 104, so that irregular reflection due to the internal electrodes 108 or vias is prevented in illumination for mounting, and mounting operability of the electronic component improved, and the generation of fog 138 is suppressed due to a reflected light 136 in the internal electrode 108 using a photosensitive resin and via holes 134 in stereoscopic molding of the vias. In this way, an electronic component in which electric characteristics are improved, and characteristic variations are suppressed, is provided.
