Abstract: The present disclosure provides a usage notification device that adds, to a refrigerator not provided with a communication function, the function of notifying a communication terminal of usage. The usage notification device includes an attachment portion, a wireless communication unit, a door open/closed recognition unit, and a notification control unit. The attachment portion attaches the usage notification device to an exterior of the refrigerator. The wireless communication unit performs a wireless communication with the communication terminal. The door open/closed recognition unit recognizes the open or closed state of the refrigerator. The notification control unit transmits the usage information on the refrigerator based on the door open or closed state of the refrigerator, to the communication terminal via the wireless communication unit.
