According to a lead wire sealing device of an example of the present invention, a bush 116 is inserted in a housing through hole 113 formed in a bottom plate member 1110 and a lead wire 1343 is inserted in the inside of the bush 116. Preferably, the catalyst contains both alumina and a molecular sieve, and the reaction is performed under relatively mild conditions such that the majority of the base material does not dissolve into the solution. When the lock is under attack, and an inward force is applied to the bolt, the detent moves so as to maintain a detent fence away from the levers. The main body of the information-processing apparatus includes a housing made of electrically-conductive material, such as metal.
