The present invention provides a highly convenient configuration with which information communication terminal equipment can confirm whether electric equipment such as an electric rice cooker has completed an operation as scheduled, and an operation start time can be automatically adjusted. The present invention is provided with: an electric heater; an input operation unit that can designate a scheduled operation mode in which a rice cooking operation is started at a predetermined time; a transmission unit that externally transmits rice cooking operation completion and non-completion notification signals; a reception unit that receives an external inquiry signal for a scheduled rice cooking state; and a control device that detects whether the operation has been completed as scheduled. If the scheduled rice cooking operation has not been performed when a scheduled set time has elapsed, the control device issues a signal for notifying that the rice cooking operation is incomplete from the transmission unit, and after the completion of the rice cooking operation, automatically issues a signal for notifying the completion of rice cooking. Moreover, the control device ascertains the present position of the information communication terminal equipment, and automatically adjusts the timing of the rice cooking operation.
