Claim 7:
8. The axial-flow fan of claim 7,
wherein in a case in which a direction along the axial direction and oriented from the leading edge toward the trailing edge is defined as a direction of airflow,
a part of the leading edge that forms the inlet angle at the point in the second line chart that is at a distance equal to the radial distance of the minimal possible point of the outlet angle represented in the first line chart is defined as a leading-edge load-bearing point, and
a point of the leading edge that is at the outer circumferential edge is defined as a leading-edge outer circumferential point,
the leading-edge load-bearing point is located downstream of the leading-edge outer circumferential point in the direction of the airflow.
