Abstract
A printing head comprising a plurality of printing electrodes positioned in parallel with each other on a surface of an electrically insulating board. Electrically conductive projections are provided in a zigzag format on the exposed portions of an electrically insulating layer of the electrically insulating board near the front edge of the plurality of printing electrodes. The electrically conductive projections are formed such that when they are projected onto a sliding surface by the printing head, the adjacent electrically conductive projections are positioned with a lateral separation distance of 50% or less of the electrically conductive projection width, or with an overlapping portion of 25% or less. Slits are provided between the printing electrodes on at least the front edge of the plurality of printing electrodes.
