PROBLEM TO BE SOLVED: To easily impart a reducing property to water, etc. SOLUTION: A couple of radiators 10 formed by coiling a couple of conductor wires 11 in parallel with the respective ends short-circuited to each other are connected in series and then connected to an oscillating circuit 20 as a bridge circuit to constitute the device. When an AC current is applied to the oscillating circuit 20, an Ac current of the low frequency of <=7 Hz is applied to the couple of radiators 10, and an electromagnetic wave made into a longitudinal wave and at a low frequency of <=7 Hz is radiated from the respective radiators 10.
