Abstract
A liquid jet head includes an ejecting portion having a first head chip and a second chip which are laminated with each other, and a circuit board which outputs a drive signal for driving the ejecting portion. A first connection board electrically connects the first head chip to the circuit board, and a second connection board electrically connects the second head chip to the circuit board. A bend portion is provided in the circuit board so that by bending the circuit board at the bend portion, the first electrode terminal portion and the second electrode terminal portion are made to extend in the same direction, and face each other in the lamination direction of the head chips. The circuit board has a connecting terminal that is exposed to the outside through a window in the circuit board when the circuit board is bent at the ending portion.
