摘要：
A circuit device capable of suppressing reduction of reliability resulting from heat generated in a circuit element is obtained. This circuit device comprises a first insulating layer having a first opening and a second opening, a first conductor filling up the first opening of the first insulating layer, a second conductor, formed along the inner side surface of the second opening of the first insulating layer, having a concave upper surface and a circuit element arranged above a region of the first insulating layer formed with the first opening.
