A cross flow fan includes a plurality of vanes arranged around a rotation axis at predetermined intervals in the circumferential direction, a tongue section arranged on the outer circumferential side of the vanes, and jetting sections that jet a fluid along the wall surfaces of a discharge path into which the fluid is discharged from each of the vanes. A facing wall section is provided to a position facing the tongue section with the vanes therebetween. The facing wall section is provided with: an upstream wall section configured so as to be equivalent to the radius of curvature in the outer circumference of a path formed when the vanes rotate; a downstream wall section that is connected to the upstream wall section and in which the radius of curvature gradually becomes larger than that of the upstream wall section; and a diffuser wall section connected to the downstream wall section.
