Zusammenfassung:The invention provides a centrifugal fan capable of suppressing generation of noise and an electronic device provided with the centrifugal fan. A centrifugal fan is provided with: a fan having a motor part that rotates about a central axis, and a plurality of blades provided on the outer periphery of the motor part; and a housing that accommodates the fan and has an air suction port provided in the axial direction of the central shaft and an air discharge port provided in the direction orthogonal to the central shaft, and an inclined portion provided on each of the end surfaces of the plurality of blades facing the air suction port, the inclined portion being inclined so as to be cut toward the motor portion. The plurality of blades include a plurality of blade groups, and the plurality of blade groups are configured in such a manner that the positions of the starting points at which the inclined parts start to incline are different in the direction from the front ends of the blades toward the motor part. 本发明
