PURPOSE: To enhance reliability by preventing a disconnection of a lead wire of a moving coil connecting a connecting terminal of a moving coil of a dot pin-driving actuator of an electric part of a printing head with a connecting terminal of a drive-controlling printed circuit board as a result of the vibration when the actuator is driven in a dot impact printer. CONSTITUTION: A flat coil 2 is connected by soldering or the like manner to a connecting terminal 2a set at a coil base 1 of a dot pin-driving actuator of a printing head of an electric part and a connecting terminal 11a set at a drive-controlling printed circuit board 11. At least a connecting base of a lead wire 8 of this flat coil 2 which is connected with the connecting terminal 11a of the printed circuit, board 11 is coated with a first hard coating layer 21 and a second gel coating layer 22 on the first coating layer 21 which is sufficiently softer than the first coating layer 21. |
