Patent ID: 7735967

Claim:
A liquid conveying substrate, comprising: a substrate; a plurality of first electrodes disposed on the substrate and arranged in a plurality of columns in a first axial direction; a plurality of first conductors respectively connecting two adjacent first electrodes of the plurality of first electrodes and arranged along the first axial direction; a plurality of second electrodes disposed on the substrate and arranged in a plurality of columns in a second axial direction crossing with the first axial direction; a plurality of second conductors respectively connecting two adjacent second electrodes of the plurality of second electrodes, arranged along the second axial direction, and crossing with the first conductors; and an insulating layer for insulating the first conductors and the second conductors, wherein the first conductor and the second conductor cross with each other in a region where the first electrodes and the second electrodes are not positioned as seen from a side where the first electrodes are substantially disposed, and the insulating layer is positioned at least in the crossing region.
