Radar device

A radar device comprising:

• a substrate including a plurality of conductor layers arranged on a front surface or a rear surface, the conductor layers comprising a plurality of high-frequency conductor layers for transferring a high frequency signal;
• a semiconductor component facing the front surface of the substrate, being in contact with the plurality of conductor layers on the substrate via conductive members, and configured to generate a high frequency signal;
• and
• an adhesive configured to bond the semiconductor component to the front surface of the substrate, wherein
• the semiconductor component has a bottom surface and a plurality of side surfaces including a first side surface facing in a first direction from a central portion to an edge in a plane of the front surface or the rear surface,
• all the plurality of high-frequency conductor layers or a high-frequency conductor layer set included in the plurality of high-frequency conductor layers includes at least high-frequency conductor layers that bend in the plane of the front surface or the rear surface and thereby extends, on the front surface or the rear surface, from inside ends facing the bottom surface to outside ends positioned in the first direction from the first side surface, and
• the adhesive is in contact with the front surface except for sites of the plurality of high-frequency conductor layers formed and in contact with the side surfaces of the semiconductor component.
