Communication device

Abstract

An object is to provide a communication device capable of appropriately storing communication information for specifying another device that performs communication at an abnormal timing. A communication device 10 is a communication device that is mounted on a vehicle and communicates with other devices. The communication device 10 includes a communication monitoring unit 40 that monitors communication with another device and accumulates communication information for specifying another device that performs communication, a storage medium 30 that stores the communication information, and a timer 22 that counts a duration of a wake-up state of the communication device 10. When the duration of the wake-up state has passed a predetermined time, the communication monitoring unit 40 stores the accumulated communication information in the storage medium 30.
