Abstract
A liquid ejection head capable of more efficiently ejecting ink and an inkjet printing apparatus are provided. The liquid ejection head has a block member which surrounds at least a part of an effective bubble-generating region involved with heat generation in a heat-generating element and which is formed so as to protrude from the heat-generating element in a direction in which a liquid is ejected. The block member is arranged in a position where a distance of a position of an inner end part from an outer end part of the effective bubble-generating region is +2 μm or less, with an outward direction being set to be positive.
