<P>PROBLEM TO BE SOLVED: To prevent discharge of static electricity held by a human body from affecting a circuit section. <P>SOLUTION: A card-type electronic key 10 comprises a battery holder 32 in which a disk-like battery 12c can be inserted or taken out by sliding from an opening 2 provided in a side face of a housing to a power supply part 12 in the housing. When the battery holder 32 has been inserted, an interval of 3 mm or more for preventing dielectric breakdown of air is provided between an end of a negative electrode terminal 12b provided in the power supply part 12 and an end of the disk-like battery 12c in the housing, in a state (102) in which a finger 33 of a human body can be contacted with the disk-like battery 12c, and an interval of 3 mm or more for preventing dielectric breakdown of air is provided between the finger 33 of the human body and the end of the disk-like battery 12c in the housing, in a state in which the negative electrode terminal 12b can be contacted with the disk-like battery 12c. <P>COPYRIGHT: (C)2013,JPO&INPIT |
