    摘要： An object is to provide a liquid ejection head and liquid ejection apparatus capable of preventing a deterioration in ink circulation efficiency in the vicinities of ejection ports. To this end, a common supply channel 18 and a common collection channel 19 are provided as separate channels. An ink supplied from the common supply channel 18 is supplied to pressure chambers 12 through supply connection channels 323, and collected from the pressure chambers 12 into the common collection channel 19 through collection connection channels 324. Also, the common supply channel and the common collection channel extend in a direction crossing a main scanning direction in which the liquid ejection head is scanned and the ejection direction of the liquid.

    摘要： Provided is a liquid ejecting head (5) and a liquid ejecting apparatus (1) that can suppress decrease in ejection accuracy while suppressing increase in cost and decrease in productivity. To this end, a sub-tank (20) is attached to a bottom of a main body part (10) with a greater number of screws (25) on the front side where the stiffness is low than that on the back side where the stiffness is high.

    摘要： An object is to provide a liquid ejection head (1) and liquid ejection apparatus capable of preventing a deterioration in ink circulation efficiency in the vicinities of ejection ports (12) and an increase in apparatus size. To this end, a common supply channel (18) and a common collection channel (19) are provided as separate channels. An ink supplied from the common supply channel is supplied to a pressure chamber (12) through a supply connection channel (323), and collected from the pressure chamber (12) into the common collection channel (324) through a collection connection channel (324). Also, the ink is caused to flow along a main scanning direction through the pressure chamber (12).
