A hand-held device is a portable device configured to be attached to and detached from a metal board, and includes a casing and a magnet disposed inside the casing so as to be attracted to the metal board via an attachment face of the casing. The hand-held device further includes an urging element for urging the magnet so that the magnet moves in a direction away from the attachment face when the casing is detached from the metal board.
