PROBLEM TO BE SOLVED: To provide a print head suitable for high speed print and high copy print by protecting a sprint against fatigue fracture. SOLUTION: An armature 1 and a spring 2 for driving the armature 1 are secured by welding and the torsional fulcrum part 3 of the spring 2 is clamped fixedly by fulcrum fixing plates 5. In such a print head, the fulcrum fixing plates 5 are shaped to be arranged not in parallel but at an angle with the longitudinal direction of the armature 1.
