Abstract
The portability of a mechanical key and a locking/unlocking key having the mechanical key is improved. The mechanical key is housed in a portable device in such a manner that a key plate is folded into two at a portion formed with an inner groove. Thus, the housing space for housing the mechanical key can be reduced and the portable device can be made smaller. Accordingly, the portability of the locking/unlocking key can be improved.
