PROBLEM TO BE SOLVED: To reduce the possibility that influence of liquid thickening occurring in a nozzle reaches the inner side of a pressure chamber and concurrently reduce an area of a liquid jet head which is viewed from a liquid jet direction.SOLUTION: A liquid jet head includes: a pressure chamber formation substrate 52 forming pressure chambers 66 filled with an ink; nozzles N which jet the ink in a Z direction along the pressure chamber formation substrate 52; and communication passages 68, each of which allows the pressure chamber 66 to communicate with the nozzle N. Each communication passage 68 includes a first passage Q1 along a Y direction that intersects with the Z direction. |
