PROBLEM TO BE SOLVED: To provide a liquid jet head which is easily produced and enables downsizing, and to provide a liquid jet device.SOLUTION: A liquid jet head includes: a liquid introduction member including a liquid introduction channel 23 which introduces a liquid from a liquid supply source, a filter chamber 25 provided with a filter 24 which filters the liquid from the liquid introduction channel 23, and a connection channel 26 which sends the liquid in the filter chamber 25 to the downstream side; and a liquid jet head body 14 which is connected with the liquid introduction member, introduces the liquid from the connection channel 26 into a pressure chamber 61 through a liquid channel 75, and generates pressure changes in the pressure chamber 61 thereby jetting the liquid from a nozzle 57 formed on a nozzle surface 58 as droplets. A parallel channel part 38 extending in parallel with the nozzle surface 58 is formed in a part of the connection channel 26. |
