The propeller fan (1) includes: a hub (2); and a plurality of blades (3) supported by the hub (2). A pressure surface (9b) of each of the plurality of blades includes a protruding portion (11) curved so as to swell to a suction side (6). A height of the protruding portion (11) of each of the plurality of blades on a trailing edge side is larger than a height of the protruding portion (11) on a leading edge side. A radial position of an apex (11c) of the protruding portion (11) on the trailing edge side is located on a radially inner side with respect to a radial position of the apex (11c) of the protruding portion (11) on the leading edge side.
