The present invention provides an electric steering locking device, capable of accurately detecting a locked position and an unlocked position by using a magnet with weak magnetism. The electric steering locking device (1) comprises a locking unit (30), a magnet (33), Hall elements (72, 73), a locked position ferro magnetic material (82) and an unlocked position ferro magnetic material (83), wherein the locked position ferro magnetic material (82) is arranged at a position corresponding to the locked position, and the Hall element (72) is clamped between the position and the magnet (33), and the locked position ferro magnetic material (82) is arranged at the position where the locked position ferro magnetic material (82) is partially superposed and projected with the Hall element (72) when projected and viewed from the direction perpendicular to a detecting surface of the Hall element (72), the unlocked position ferro magnetic material (83) is arranged at a position corresponding to the unlocked position, and the Hall element (73) at the unlocked position is clamped between the position and the magnet (33), and the unlocked position ferro magnetic material (83) is arranged at the position where the unlocked position ferro magnetic material (83) is partially superposed and projected with the Hall element (73) when projected and viewed from the direction perpendicular to a detecting surface of the Hall element (73).
