Claim:
1. A pair of sliding components provided, on a high-pressure side of one of relatively sliding sealing faces thereof, with a fluid discharge for discharging fluid to high-pressure fluid side, wherein a positive pressure generating mechanism for generating a positive pressure is provided in the sealing face on a high-pressure side of the fluid discharge such that the positive pressure generating mechanism is isolated from the high-pressure fluid side by a land portion; an annular pressure releasing groove is provided between the fluid discharge and the positive pressure generating mechanism, the pressure releasing groove is connected to a discharge-side end of the fluid discharge and is separated from the positive pressure generating mechanism in a radial direction by a land part; and a radial groove is provided to communicate the pressure releasing groove and the high-pressure fluid side with each other, and the radial groove is provided to be in contact with an upstream end of the positive pressure generating mechanism.
