。 a core that forms part of a magnetic path with the yoke; an armature that is disposed opposite to the front end surface of the core;
A printing wire fixed to the armature,
A wire guide member that guides the wire during printing operation, a spring member that always applies a forward spring force to the armature, and a magnetic pole for attracting the armature that overcomes the spring force on the front end surface of the core. and a coil that is wound around the core and generates a magnetic flux that eliminates the armature attraction force when energized, and the wire is connected to a metal base material and a hardened layer formed on the surface of the base material. A dot impact head characterized in that the hardened layer is made of ceramic.
