The utility model discloses a fan blade component and fan. This fan blade component includes a plurality of fan blades of arranging along the circumferencial direction, has the contained angle between the adjacent fan blade in the contained angle, have at least the number of degrees of a contained angle different with the number of degrees of other contained angles. The utility model provides a plurality of fan blades of fan blade component are not along the circumferencial direction equipartition, but have at least the contained angle number of degrees between the adjacent fan blade with other of contained angle between the two adjacent fan blades different, and the not equally spaced mode of arranging of this kind can effectively weaken the fan blade to gaseous sexual periodicity pressure fluctuation, and then reduce the discrete frequency noise of fan blade, improvement use comfort.
