Abstract

In a channel member 11 of a head 10, common channels 31 to 34 and recesses 51 to 54 overlapping with the common channels 31 to 34, respectively, in a Z direction are formed. Lengths in a X direction of the common channels 31 to 34 are substantially same as one another. A length W52 in a Y direction of the recess 52 is shorter than a length W53 in the Y direction of the recess 53. Compliance of a film 132 defining the common channel 32 is smaller than compliance of a film 133 defining the common channel 33. A length W54 in the Y direction of the recess 54 is shorter than a length W51 in the Y direction of the recess 51. Compliance of a film 134 defining the common channel 34 is smaller than compliance of a film 131 defining the common channel 31. It is possible to make the characteristic periods of the two common channels to be mutually different and to suppress any non-uniformity in density, even without changing the volumes of the two common channels to be mutually different.
