PROBLEM TO BE SOLVED: To provide a concrete form separator plug capable of facilitating the connection of a sleeve to a nut member and the screwing of a bolt for mounting the plug to a form on the nut member and, at the same time, facilitating the change of the length of the sleeve corresponding to the dimension of cover concrete. SOLUTION: A ring-shaped magnet body 16 is stuck on one end of the sleeve 14 comprised of a fine ceramic formed in the shape of a cylinder by burning an inorganic material, the metal-made nut member 15 having a female screw 15a on the inside circumference is absorbed in the magnet body 16, and a separator 2 and the bolt 3 are screwed on the female screws 15a.
