Circuit board with built-in electronic component and method for manufacturing the same

A circuit board with a built-in electronic component comprising an insulating layer, a first wiring pattern provided on a first main surface of the insulating layer, a second wiring pattern provided on a second main surface different from the first main surface of the insulating layer, and at least one electronic component provided in an internal portion of the insulating layer;

• wherein the electronic component comprises a first surface and a second surface that are two different surfaces, a first external connection terminal formed on the first surface and a second external connection terminal formed on the second surface of the electronic component;
• wherein the first external connection terminal is connected electrically to the first wiring pattern, and the second external connection terminal is connected electrically to the second wiring pattern;
• and
• wherein the electronic component is formed by attaching plural semiconductor chips to a semiconductor chip with an adhesive.
