A vehicular communication device is provided. The vehicular communication device includes a reception section that receives, from a periphery vehicle equipped with a narrow area communicator for performing vehicle interior communication, a communication performance index representing performance of the narrow area communicator, and a controller. The controller includes: a reference value setup section that successively sets a reference value of the communication performance index based on the communication performance indexes received from multiple the periphery vehicles; an acquisition section that acquires the communication performance index for a targeted narrow area communicator; and an anomaly determination section that determines anomaly of the targeted narrow area communicator, based on comparison between the reference value set by the reference value setup section and the communication performance index acquired by the acquisition section for the targeted narrow area communicator.
