PROBLEM TO BE SOLVED: To provide an indoor unit having a louver by which separation of an airflow is inhibited and in which occurrence of a surface sink by molding is inhibited.SOLUTION: Multiple grooves G, which are indented toward a first surface 71 side and extend in a direction that intersects with an airflow direction, are disposed on a second surface 72 of a louver 70 so as to be aligned in the airflow direction. The peak of a groove depth d of the multiple grooves G exists in an area on a leading edge 73 side of the louver 70, and the groove depth d of the multiple grooves G gradually increases toward the peak position of the groove depth d from the leading edge 73 side, and gradually decreases toward a trailing edge 74 side from the peak position of the groove depth d. The peak position of the groove depth d is disposed in an area corresponding to the peak position of a blade thickness T. |
