Abstract: The present invention provides a print head that allows the characteristics of ejected ink to be adjusted for each ejection port in spite of a variation in the distance from an ink supply port to the heating element. In the print head according to the present invention, the area of the heating element decreases with increasing distance from the ink supply port and increases with decreasing distance from the ink supply port. The heating element is shaped like a rectangle that is longer in a direction orthogonal to a direction in which the plurality of ejection ports are arranged than in the direction in which the plurality of ejection ports are arranged. The aspect ratio of the heating element depends on the length of an ink channel through which ink is introduced into the bubbling chamber.

Abstract: When each of an energy acting chamber and a second ejection port portion is partitioned by a first virtual plane into an area positioned on a first side of the first virtual plane and an area positioned on a second side of the first virtual plane, the energy acting chamber has a larger volume in the first side area than in the second side area. Conversely, the second ejection port portion has a smaller volume in the first side area than in the second side area. The first virtual plane is parallel to both a supply direction of a liquid flowing to the energy acting chamber and an ejection direction, and passes through a center of a heating element. The first virtual plane divides each of the energy acting chamber and the second ejection port portion into two parts in an orthogonal direction orthogonal to the supply direction.
