PROBLEM TO BE SOLVED: To provide a non-electromagnetic wave thermoregulator for heating wire of bedclothes, which can heat freely from electromagnetic wave and can detect a temperature even with an end of a heating wire not being short-circuited, where the heating wire is used in an electric carpet, an electric blanket, an electric wet pad, and the like. SOLUTION: The non-electromagnetic wave thermoregulator for heating wire comprises: a temperature adjusting controller which is connected to the heating wire including a first and second heating wires arranged in parallel to each other and an NTC thermistor, checks a temperature signal voltage output from the first heating wire against a reference voltage, and outputs a temperature control signal; and a controlling rectifier which forces a heating current to flow from the opposite end to an end of the second heating wire connected to a power source through an end and the other end of the first heating wire back to the side of the power source when the temperature adjusting controller controls conduction, where magnetic fields of the heating wires cancel out to create a non-magnetic field in detecting the temperature and heating.
