Abstract
A vehicle radar apparatus includes an antenna board provided with an antenna unit configured to transmit and receive a radio wave on one side surface, a high-frequency circuit being provided on the surface of the antenna board and configured to generate the radio wave to be transmitted and perform processing of the received radar wave, and a case configured to accommodate the antenna board and the high-frequency circuit. The case includes a cover portion that is provided so as to cover the surface side of the antenna board. The cover portion includes a transmission portion configured to transmit the radio wave, and a heat conduction portion having a thermal conductivity higher than a thermal conductivity of the transmission portion. The heat conduction portion is configured to be in contact with the high-frequency circuit directly or via an indirect member.
