An impeller of a multiblade blower capable of reducing noise and increasing air blow performance and the multiblade blower having the impeller. The impeller (113) of the multiblade blower (110) comprises a disk-like main plate (131) rotating about its rotating axis, a plurality of blades (133), and a side plate (132). The plurality of blades (133) are disposed on one surface of the main plate (131) annularly about its rotating axis, and one ends thereof are fixed to the outer peripheral part of the main plate (131). The side plate (132) comprises an annular side plate body part (132a) connecting the other end outer peripheral edges of the plurality of blades (133) to each other, an axially extended part (132b) extending from the anti-main plate side end of the side plate body part (132a) to the anti-main plate side of the anti-main plate side end of the blades (133) in the rotating axis direction, and a radially extended part (132c) extending from the outer peripheral end of the side plate body part (132a) to the outer peripheral side of the radial outer peripheral end of the axially extended part (132b). |
