To provide a circuit device freed from constrains of a mounting direction. The circuit device according to the present invention includes: a conductive pattern for forming a die pad, a first bonding pad, and a second bonding pad; and a semiconductor element (TR) attached to the conductive pattern. The circuit device further includes: a sealing resin for covering the semiconductor element (TR) and the conductive pattern with a rear surface of the conductive pattern being exposed; and a coating resin for covering the rear surface of the conductive pattern exposed from the sealing resin. The rear surface of the conductive pattern is exposed from openings of the coating resin, and the openings are arranged with rotational symmetry about a central point of the circuit device.
