The communication device has: a receiving section for receiving a signal from the opposite side communication device; a measurement section for measuring a communication time per bit from a received prescribed signal, when the baud rate of the opposite side communication device does not match, and specifying the baud rate of the opposite side communication device on the basis of the communication time per bit thus measured; and a second determination unit for determining whether or not the specified baud rate is the first baud rate or less. The communication device has a control section for controlling the setting section so as to set a baud rate, of the specified baud rate or less, as the first baud rate among multiple baud rates that can be set, when the specified baud rate is the first baud rate or less.SELECTED DRAWING: Figure 2
