PURPOSE:To provide a high density electrode head enabling high resolving recording, by using pagodite as the fixing material of an elongated electric conductor and exposing only the leading end of said electric conductor. CONSTITUTION:An electrode head is constituted so that groove processing is applied to pagodite 12 at pitches of 100mum by using a dicing saw so as to form grooves each having a width and a depth both of which are 50mum and copper wires 11 are engaged with the grooves as elongated electric conductors and subsequently pressed and fixed by pagodite 13 same to the aforementioned pagodite 12. Because this electrode head is constituted so that electrodes are embedded in the fixing material without being protruded and only the leading end parts thereof are exposed, a fine electrode may be used and, because the length of each electrode can be freely selected, the high resolving long life electrode head is enabled. Because pagodite is used as the fixing material, recording paper is not damaged even if the electrode head is moved in a state pressed to the recording paper and printing quality becomes excellent. |
