PROBLEM TO BE SOLVED: To eliminate the need for a power source for ion generation and a high voltage and special electrodes for enhancing ion generation efficiency by sticking two kinds of metals varying in ionization tendency to each other across a plastic film having a good insulating characteristic in-between and using the ions generated at the cut section thereof as an ion source for sterilization. SOLUTION: Foil 1 of aluminum and copper foil 3 which are two kinds of the metals varying in the ionization tendency to each other are stuck to each other across a polyethylene terephthalate(PET) film 2 as the insulator held in-between and, thereafter, the PET film 4 for protection is also stuck to the opposite surface of the aluminum foil 1 and the copper foil 3. This laminate is cut to fine pieces and is formed to a tape form. The tape formed by sticking the metals varying in the ionization tendency to each other via the insulating film, then cutting the film to a prescribed width forms a local battery at the section of this tape and the generated ions have sterilizing power and, therefore, the tape is capable of making an important contribution in imparting sterilizing power to daily articles and industrial articles. |
