<p><P>PROBLEM TO BE SOLVED: To widely secure a width of a substrate for an interface and to thin a width of a printing head. <P>SOLUTION: The printing head has a recording unit where recording elements are arranged, a line-shaped heat sink block 31 with the recording unit set on its upper face, and an interface substrate 5. The heat sink block has a rectangular shape longer in an up-down direction when seen from a direction orthogonal to a line direction, which fixes the interface substrate to its side face. <P>COPYRIGHT: (C)2004,JPO</p> |
