In the wire printing head, the armature is attracted to the one end surface by the magnetic flux of the magnet to bend the leaf spring, and the magnetic flux of the permanent magnet is canceled by the biasing of the electromagnet to drive the printing wire fixed to the armature. A wire printing head characterized in that a groove is provided on the coil winding surface of the core and at an end corresponding to one end surface of the core.
