Summary:A communication apparatus, which is mounted in a smart meter, includes: a secondary battery; a transmitter-receiver circuit that is operable by using electric power supplied from the secondary battery; and an antenna that emits a wireless signal based on a transmission signal, which is output from the transmitter-receiver circuit, to a space, wherein the secondary battery is a lithium-ion battery; and wherein when electric power supplied from outside to the smart meter is cut off, the transmitter-receiver circuit outputs the transmission signal indicating a specified alarm to the antenna by using the electric power supplied from the secondary battery and thereby wirelessly transmits the alarm via the antenna.
