PROBLEM TO BE SOLVED: To provide a magnetic head for magnetic display capable of embodying a higher density of magnetic printing dots by greatly increasing the number of wirings of a circuit board for supplying currents to an electromagnet coil. SOLUTION: The magnetic head 30 is composed of a front yoke 40 which is formed with plural gap holes 40b, a base yoke 39 which forms magnetic circuits together with this front yoke 40, plural magnetic cores 37 which are inserted at their front ends into the gap holes 40b and generate dotty magnetic fields for recording by magnetically coupling the front yoke 40 and the base yoke 39, the electromagnet coil 38 which supply the magnetic fields to the magnetic cores 37 in accordance with the printing signals, the circuit board 42 which is arranged on the rear surface side of the base yoke 39 and electrically connect the yoke to the connecting terminal 38c of the electromagnet coil 38 and an insulating spacer 41 which is interposed between the circuit board 42 and the base yoke 39. |
