To improve reliability in various service forms for vehicles.SOLUTION: A communication device according to the present invention is a communication device mounted on a vehicle, which comprises: a detection unit which detects an output voltage value from a battery mounted on the vehicle; and a transmission unit which, when a reduction aspect of the output voltage value detected by the detection unit satisfies a reference, transmits a signal indicating the fact to an external device using power of a sub-battery mounted on the communication device. The case where the reduction aspect of the output voltage value satisfies the reference includes a case where an absolute value of the reduction amount of the output voltage value per unit time is larger than a reference value.SELECTED DRAWING: Figure 1
