    Abstract: A vehicle-mounted millimeter-wave communication device for performing communication while temporally changing a communication direction by using an antenna unit capable of changing directivity includes: a detection unit configured to detect a direction of a communication partner present around a host vehicle; and a communication control unit configured to perform control such that communication is performed, in which a longer communication time is set for the direction of the communication partner than another direction. The communication control unit preferably performs control that sets a long communication time for the direction of the communication partner in the case where the type of the content of communication with the communication partner is related to control of a vehicle, and in the case where the volume of the communication with the communication partner is not less than a threshold value.
