PROBLEM TO BE SOLVED: To continue the transfer of transmission information while suppressing a communication cost and communication time when a communication error occurs in the middle of the transfer route of broadcast transmission. SOLUTION: The communication device, capable of executing the broadcast transmission of transferring the same transmission information from an origin device to a plurality of destinations on a preset transfer route while passing through them in the order, includes: a receiving module for receiving the transmission information; a storage module for storing the received transmission information and a transfer destination information; a transmission module for transmitting the transmission information to the next device; and an error detection module for detecting a transmission error which makes it impossible to transfer the transmission information to the next device. Then, when the error detection module detects a communication error, the transmission information is transferred to the closest device on the transfer route downstream side of the next device.
