摘要： PROBLEM TO BE SOLVED: To provide a metal detection apparatus which solves the problem that a worker must carry out a troubling operation such as pushing a reset switch button in order to reset current-carrying for a shut-down electric drill in a conventional metal detection apparatus.SOLUTION: The metal detection apparatus has: a power supplying section which has a power plug 11 connected to a commercial outlet 40, a power receptacle 12 to which a plug 35 of the electric drill 30 is connected, a power supplying circuit for connecting the power plug and the power receptacle, and a switch 20 arranged on the way thereto; metal detection sections 15, 16 which are circuits connecting an earth terminal E of the power plug and an earth terminal E of the power receptacle, and detects that the electric drill has abutted against a metal 51 and has been isolated from it; and a power-supply control part 19 which turns off the switch 20 to break power supplying from the power plug to the power receptacle when detecting that the electric drill has abutted against the metal, and turns on the switch 20 to reset power supplying from the power plug to the power receptacle when detecting that the electric drill has been isolated from the metal.
