Alternatively, in a wire printing head that prints using a printing wire attached to the tip of the armature after restoration, an interference part that comes into pressure contact with the yoke and interferes with the deflection of the leaf spring when the leaf spring is attracted is moved from the rotational fulcrum of the leaf spring. A wire printing head characterized by being formed so as to be located on the fixed end side.
