PURPOSE:The recorder obtained at low cost and capable of recording with high resolution, by using the electrode head exposed by forming the end surfaces of plural pieces of electric conductors built up on an electric insulating substrate formed in V-shape. CONSTITUTION:The electric conductor 207 such as copper foil or the like is built up on the electric insulator 206 made of material such as epoxy resin series or the like, and the end surface thereof is formed in V-shape so that the electric conductor is exposed. The end surface of electrode body 205 moves in the direction of arrow mark being pressed against the surface of spark-stencil recording paper 201. The electric conductor is not bent and warped, and the dust generated during recording becomes difficult to be accumulated on the end surface of electrode head. |
