An aerofoil (20) for a gas turbine engine (10) is hollow to define an interior volume (24) through which cooling air flows. Passages (26) interconnect the interior volume (24) with the exterior of the aerofoil (20). Each passage (26) is provided with an inlet (32) within the interior volume (24) which is elongated along an axis (36) parallel with the direction of cooling air flow through the interior volume (24). The arrangement reduces any tendency for the passages (24) to block though the build up of dirt particles.
