discharge ports which discharge liquid onto a recording medium for recording on the recording medium; and

a plurality of base plates (or substrates) arranged in a zigzag shape along a longitudinal direction of the base plates, each base plates having a plurality of discharge port rows having discharge ports arranged in the longitudinal direction, said plurality of discharge port rows being arranged in a direction orthogonal to the longitudinal direction,

wherein said base plates comprise a first base plate, a second base plate adjacent to a side of one end portion of the first base plate, and a third base plate adjacent to a side of the other end portion, opposite to the one end portion, of the first base plate;

wherein in the direction orthogonal to the longitudinal direction, a distance between the discharge port rows in each of the first base plate, the second base plate and the third base plate is equal to a distance between the discharge port row on a second base plate side of the first base plate and the discharge port row on a first base plate side of the second base plate, and

wherein regarding a first line which connects the discharge ports on a side of one end portion of the first base plate, a second line which connects the discharge ports at an end portion on the first base plate side of the second base plate, a third line which connects the discharge ports on a side of the other end portion of the first base plate, and a fourth line which connects the discharge ports at an end portion on the first base plate side of the third base plate; the first line and the second line are located on the same line, the third line and the fourth line are located on the same line, and the first line and the third line intersect with each other.
