Abstract
A single recording head is provided which includes a set of plural head units each having a substrate and plural recording elements arranged on the substrate, whereby a line type recording head which is long in a main scanning direction can be manufactured easily and in high yield. The head units are arranged to be inclined so that the rows of recording elements are inclined in the main scanning direction, whereby the arrangement pitch of recording elements in a sub scanning direction is narrowed to permit a high definition recording. The inclined arrangement of the head units, moreover, is made so that the recording elements located at the same position on the substrates of separate head units lie on the same main scanning line, whereby an increase of size in the sub scanning direction is prevented and a reduction of the entire size is attained.
