PURPOSE:To obtain a printer capable of performing stable recording and not damaging a film, by providing a recording electrode of which the leading end is formed into a spherical shape to circular arc shaped protruded part in a slightly protruded state while arranging an opposed electrode to the circumferential vicinity of said recording electrode. CONSTITUTION:Because a recording electrode 2 is arranged to the top part of the circular arc shaped protruded part 14 of a head 12, a recording film 1 is easily brought into contact with the recording electrode 2 while contact pressure between both of them becomes sufficient and good recording is performed. In this case, because the recording electrode 2 is slightly protruded, the contact between both of them is further improved. In addition, because the recording film 2 is moved while contacted with the recording electrode 2 but the leading end of the recording electrode 2 is spherical, friction resistance is low and the durability of the recording film is increased. Further, because an opposed electrode 3 is provided in the vicinity of the recording electrode 2 while the contact part with the recording film 1 is provided in two places before and after the recording electrode 2 and a current is flowed in parallel as shown by an arrow, voltage to be applied is reduced and, at the same time, stable printing is obtained. |
