PROBLEM TO BE SOLVED: To provide a door stopper device which prevents a metallic stopper plate from making direct contact with a magnet by housing the magnet in a case. SOLUTION: The door stopper device is formed of a door-side device 61 and a floor-side device 50. The door-side device 61 is formed of the case 62 fixed to a door D and the magnet 73 housed in the case 62. The case 62 has a bottom wall 68 on which an engaging projection 69 is formed. The floor-side device 50 is formed of a base 53 fixed on a floor surface F, and the metallic stopper plate 52 rotatably mounted on the base 53. When the door D is opened and the door-side device 61 is disposed above the floor-side device 61, the metallic stopper plate 52 is rotated upward by the magnet 73 of the door-side device 61, and then the metallic stopper plate 52 abuts on the bottom wall 68 of the case 62 to be engaged with the engaging projection 69, to thereby restrict opening/closing of the door D.
