The magnetic attraction force generated when the magnetic flux of the permanent magnet passes through the magnetic circuit including the armature and the core causes the armature to be attracted to the core and at the same time elastically deforms the leaf spring, thereby separating the free end side and the fixed end of the leaf spring. By creating a step between the two sides and energizing the coil to cancel the magnetic flux of the permanent magnet, when the armature is released from the magnetic attraction force, the armature is rotated by the recovery force of the leaf spring, and the printing wire is rotated. In the wire dot printing head to be driven, a magnetic resin of a predetermined thickness made of a magnetic material is used to fix the core side surface of the armature and the free end of the leaf spring by welding, and to obtain the step on the leaf spring. A wire printing head characterized in that a sheet is interposed between the leaf spring and the core, or the height of the core is made higher than the fixed end of the leaf spring by a predetermined dimension.
