PROBLEM TO BE SOLVED: To optimize the area of a filter mounted in a liquid jet head.SOLUTION: An area S of a filter 51 is made to be expressed by a relational expression, provided that μ is a viscosity of the ink; Q is a maximum value of a flow rate of the liquid flowing through the filter 51 when the ink is jetted from the nozzle; N is the number of through-holes 52 per unit area of the filter 51; d is a diameter of the through-holes 52 in the filter 51; &Dgr;Pis an upper limit of a pressure loss in the liquid at the filter 51; αis a cake pulling resistance of the liquid flowing through the filter 51, C is a particle density of the liquid flowing through the filter 51; Vis a maximum value of a total volume of the liquid flowing through the filter 51 while the device is used, a and b are constants expressed by a specific relational expression; and L is a thickness of the filter 51. |
