PURPOSE:To enhance the vibration resistance, shock resistance and insulation of a printing head, by a construction wherein lead wires connected to end parts of a winding of a coil are adhered to the outside surface of the coil, are passed through a base in the condition of being insulated from the base, and are made to protrude from the base. CONSTITUTION:Ends of the winding 15a of the coil 15 are led out to the exterior of a printing head through the large diameter lead wires 18, and the length of the winding 15a between a main body of the coil 15 and the lead wire 18 is minimized. The lead wires 18 are adhered to the outside surface of the coil 15 by an electrically insulating adhesive 22, and an electrically insulating adhesive is packed in through-holes 2 to electrically insulate the base 4 and the lead wires 18 from each other. |
