<p>On a second surface (72) of a louver (70) of an indoor unit (10), a plurality of grooves (G) recessed toward a first surface (71) side and extending in a direction crossing an air flow direction are provided side-by-side in the air flow direction. A peak of a groove depth (d) in the plurality of grooves (G) is present in a region on a leading edge (73) side in the louver (70). The groove depths (d) in the plurality of grooves (G) gradually increase from the leading edge (73) side toward a position of the peak of the groove depth (d) and gradually decrease from the position of the peak of the groove depth (d) toward a trailing edge side (74). The position of the peak of the groove depth (d) is provided in a region corresponding to a position of a peak of a blade thickness (T).</p> |
