Disclosed are: a blower fan capable of reducing noise and power consumption; and an air conditioner having the same. The present device comprises: a hub connected to a driving member so as to receive rotating power; and a plurality of wings radially arranged along the circumference of the hub, wherein the plurality of wings can comprise: uneven parts formed at trailing edges, which are the rear edge portions of each wing, with respect to the rotational direction thereof; and tail wing parts formed on the outer sides of the uneven parts so as to have convex parts protruding farther than the uneven parts. La présente invention concerne un ventilateur de soufflante, lequel ventilateur est apte à réduire le bruit et la consommation d'énergie ; et un climatiseur le comprenant. Le dispositif selon l'invention comprend : un moyeu relié à un élément d'entraînement de façon à recevoir une puissance de rotation ; et une pluralité d'ailes disposées radialement le long de la périphérie du moyeu, la pluralité d'ailes pouvant comprendre : des parties irrégulières formées au niveau de bords de fuite, ces dernières étant les parties de bord arrière de chaque aile, par rapport à la direction de rotation de cette dernière ; et des parties d'aile arrière formées sur les côtés externes des parties irrégulières de façon à avoir des parties convexes faisant saillie plus loin que les parties irrégulières. 소음과 소비전력을 줄일 수 있는 송풍팬 및 이를 구비하는 공기 조화기가 개시된다. 본 장치는, 구동부재와 연결되어 회전력을 전달받는 허브; 및 허브의 원주에 방사상으로 배치된 복수의 날개;를 포함하고, 복수의 날개는, 회전방향을 기준으로 각 날개의 후방 모서리 부분인 트레일링 에지에 형성되는 요철부; 및 요철부의 외측에 형성되어 요철부보다 돌출되는 볼록부를 가지는 꼬리날개부;를 포함할 수 있다.
