Abstract: A radar apparatus includes a circuit board including a board surface provided with an antenna module for transmitting an electromagnetic wave, a housing accommodating the circuit board and including a facing wall facing the board surface, and a heat transfer module transferring heat generated inside the housing to the housing. The facing wall includes a transmission portion transmitting therethrough the electromagnetic wave transmitted from the antenna module and an absorption portion having a thickness different from the thickness of the transmission portion and absorbing the electromagnetic wave which is incident. The heat transfer module includes a first transfer member placed to be in contact with the absorption portion in the housing and a second transfer member transferring the heat to the first transfer member.
