The invention relates to the field of axial-flow type fans, and provides an axial-flow type fan. The axial-flow type fan comprises a hub and multiple fan blades which are arranged on the hub in the circumferential direction, and tilting parts which tilt towards the axial-flow direction are formed in the blade tip parts of the fan blades. Through the arrangement of the tilting parts which tilt forward on the fan blades, pressure in the blade tip areas of the front sides of the fan blades can be elevated and a high hydrostatic pressure area is formed, so that on the pressure surface of the fan blades, more airflow firstly flows to the center of the fan blades, then breaks away from the fan blades and forms a wind cone, and in the middle part of the wind cone, the airflow velocity can be higher, and the air supplying distance can be longer.
