A primary objective of a sliding element of the present invention is to decrease a friction coefficient of the sliding face and to improve seal performance thereof. The sliding element comprises a first dam section ( 6 ) which is configured in an annular form on the sliding face ( 2 ), a second dimple section ( 3 A) which has a form of a narrow groove and makes an inclination angle (beta) being measured from the dam section ( 6 ) in a direction of rotation pointing toward the sealed fluid, a suction means ( 3 ) which includes an annularly arranged array of the second dimple sections ( 3 A), a first dimple section ( 4 A) which has a form of a narrow groove and makes an inclination angle (alpha) being measured from the dam section ( 6 ) in a direction of rotation pointing an opposite direction relative to the suction means ( 3 ), a discharge means ( 4 ) which includes an annularly arranged array of the first dimple sections ( 4 A), and a seal face ( 7 ) which is disposed in a peripheral surface adjacent to the discharge means ( 4 ) and in the opposite side relative to the dam section ( 6 ).
