Zusammenfassung:	PURPOSE:To provide a magnet body for a nail gun which is advantageous for suppressing the trouble of the crack, chipping, etc., of a permanent magnet part in the nail striking, etc. CONSTITUTION:On the body 2 of a nail gun 1, a nail receiving part 25, holding hole 24, and a striking body 30 are installed, and a magnet body 4 is fitted with the holding hole 24. The magnet body 4 is constituted of a sintered magnet part 40 and a pramag part 42 which is formed by covering the whole of the sintered magnet part 40. In the state where the sintered magnet part 40 is arranged in the cavity of a shaping mold, the mixed material containing the Nd-Fe-B group rareeath group magnetic powder and the polyamide resin is solidified through the injection molding into the cavity, and the magnet body 4 is constituted.
