Three-dimensional circuit structure
An electronic component ( 11 ) is embedded in an end portion of a surface (P 1 ) and an end portion of a surface (P 2 ) adjacent to each other in a three-dimensional base ( 2 ). The portion of an electrode ( 21 ) exposed from the surface (P 1 ) and an electrode ( 101 ) of a packaged IC ( 41 ) are connected to each other via a wiring line ( 201 ). The portion of the electrode ( 21 ) exposed from the surface (P 2 ) and an electrode ( 25 ) of an electronic component ( 15 ) are connected to each other via a wiring line ( 202 ). Accordingly, it is possible to realize a three-dimensional circuit structure requiring no wiring line spanning over or along an end portion thereof.
1. A three-dimensional circuit structure comprising:
a three-dimensional base at least having a first surface and a second surface connected to the first surface in non-parallel;
first electronic component including (i) one electrode at least having a first portion exposed from the first surface and a second portion exposed from the second surface and (ii) an other electrode, the first electronic component being embedded in an end portion of the first surface and an end portion of the second surface adjacent to each other in the three-dimensional base, the first electronic component being a passive component;
a second electronic component embedded in the first surface;
a third electronic component embedded in the second surface;
a first wiring line on the first surface, the first wiring line being connected to the first portion and the second electronic component at the first surface; and
a second wiring line on the second surface, the second wiring line being connected to the second portion and the third electronic component at the second surface.
