Abstract
A sliding component includes a plurality of dynamic pressure generation mechanisms circumferentially arranged on a sliding surface of the sliding component. Each dynamic pressure generation mechanism includes an introduction groove portion communicating with a sealing target fluid side through an opening portion of the introduction groove portion and a dynamic pressure generation groove portion communicating with the introduction groove portion and extending in a circumferential direction in which the sliding component is relatively rotated with respect to a mating sliding component. The introduction groove portion is partially defined by a boundary wall positioned between the introduction groove portion and the dynamic pressure generation groove portion. The boundary wall has an inclined surface where at least a portion of the boundary wall positioned on a side of the opening portion extends toward the sealing target fluid side and inclined to a side of the dynamic pressure generation groove portion.
