摘要： The present invention provides a liquid ejection head which includes a plurality of ejection ports 302 arranged so as to form an ejection port row and which, after a recovery process of expanding and transferring a bubble toward an ink supply port, allows the bubble to be smoothly removed from a nozzle 310. electrothermal transducing element A plurality of nozzle filters 306 are arranged between an ink supply port and the ink channel 304 so that ink supplied to the bubbling chamber 303 through the ink supply port is passed between the nozzle filters 306 to separate impurities contained in the ink, from the ink. When a distance between an ink channel inlet 311 and the nozzle filter 306 is defined as L1 and a distance between the adjacent nozzle filters 306 is defined as L2, a relationship between L1 and L2 satisfies L1≦L2.

摘要： A recording head includes a substrate whose first surface has an element that generates energy used for ejecting liquid; a first portion that supports a second surface of the substrate; a wiring member having multiple electrode leads connected to multiple electrode pads provided in the substrate; a second portion that supports the wiring member; and a sealant that seals a section including a connection section between the electrode pads and the electrode leads. A region surrounded by the substrate, the second portion, and the electrode leads is provided with an ascending portion that increases in height in a direction extending from the second surface toward the first surface, the ascending portion increasing in height from a first end to a second end of the region in an arrayed direction of the electrode leads.
