<p><P>PROBLEM TO BE SOLVED: To provide an anti-surge defense device which has quick response speed and can automatically be used repeatedly, and to provide its manufacturing method. <P>SOLUTION: In the method for forming a high resistance film by oxidizing the surface of a metal rod, at first, a first oxidation for bringing a plurality of metal rods into contact and integrating them is carried out, and then a second oxidation for forming the high-resistance film on the entire plural metal rods is carried out. Although oxidation conditions normally differ between the first oxidation and the second oxidation, they may be the same. In this process, a plurality of metal rods are integrally connected via the high-resistance film, and a structure having the high-resistance film on the entire metal rod is formed. Thereafter, an electrode is connected to both ends of the entire metal rod by means of solder or a conductive adhesive material, thus becoming a major structure of the anti-surge defense device. The number and the size of the metal rods and first and second oxidation conditions are chosen according to the use. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
