The magnetic flux of the permanent magnet passing through the core and armature arranged in the core attracts the armature to the attraction surface of the core, biasing the bias leaf spring, exciting the coil wound around the core, canceling the magnetic flux of the permanent magnet, and causing the armature to move. In the wire dot printing head that prints dots with a printing wire, the suction surface of the core and the leaf spring support surface of the second support member are flush with each other, and the end of the leaf spring support surface of the first support member is released. A wire dot printing head, characterized in that a convex portion is provided on a portion thereof to elastically deform the bias plate spring toward the first support member.
