(57) [Summary] [Problem] A cluster is small, has a far-infrared effect, It can efficiently absorb far-infrared rays and convert it to heat, Moreover, apply to all liquids. SOLUTION: A ceramic having an extremely high far-infrared emissivity is immersed in water so as to have a weight ratio of 10% or more with respect to the weight of the water, and a first-class ground is connected to the water. It is characterized in that the electrode is put in, and in this state, it is left for a certain time. |
