PURPOSE: An electric bed and a manufacturing method thereof are provided to protect a user from an electronic wave and confirm an operating state of a bed. CONSTITUTION: A remote controller(72) outputs a control signal for controlling a heater and a magnetic field generating coil. The first controller(102) controls drivings of the heater and the magnetic field generating coil according to the control signal from the remote controller(72). A telephone signal transceiver circuit(122) transmits and receives a telephone signal between a telephone set and the first controller(102) in order to control the heater and the magnetic field generating coil through a telephone by a user and output operating states of the heater and the magnetic field generating coil as sounds. A remote control signal transceiver(118) performs a bilateral communication between the remote controller(72) and the first controller(102). An operating panel inputs a user operation command with respect to operation of the heater and the magnetic field generating coil and displays a set temperature.
