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, a communication performance index representing performance of the narrow area communicator, and controller. The controller includes a reference value setup section that successively settles a reference value as a criterion for the communication performance index based on the communication performance indexes received from multiple periphery vehicles, an acquisition section that acquires the communication performance index for a targeted narrow area communicator serving as the narrow area communicator targeted at anomaly determination, and an anomaly determination section that determines an anomaly of the targeted narrow area communicator based on comparison between the reference value settled by the reference value setup section and the communication performance index acquired by the acquisition section for the targeted narrow area communicator.
