<P>PROBLEM TO BE SOLVED: To provide a lightning current detection sensor having a structure which withstands a high voltage and a high current at a time of lightning and which has a high sensitivity and a high resolution. <P>SOLUTION: The detection area of a lightning current detection sensor 10 is made to be minute and the resolution of the lightning current detection sensor 10 is enhanced even when an insulation coating wire is wound a plurality of number of times in order to improve sensitivity, by covering an insulation coating electric wire 22 consisting of an insulation coating wire wound a plurality of number of times with a base tape 21 and a cover tape 23. In addition to the base tape 21 and the cover tape 23 covering the insulation coating electric wire 22, a shield part 12 consisting of an insulator and an air gap 40 formed between the shield part 12 and a coil part 20 ensure a sufficient shielding property, and high accuracy detection can be performed also with respect to a high current and a high voltage, without capacitive coupling. <P>COPYRIGHT: (C)2012,JPO&INPIT |
