Abstract
An air conditioner includes an air conditioning case, a blower fan, and a facing wall portion. The air conditioning case configures an air passage through which air to be blown into an interior flows. The blower fan is disposed inside the air conditioning case. The facing wall portion is disposed on an air flow upstream side of the blower fan to face a suction port of the blower fan. The air conditioning case has a facing surface that faces the facing wall portion and in which through holes are formed. The air conditioning case has a closed space formed therein on an opposite side of the facing surface with respect to the air passage and communicating with the air passage via the through holes. The through holes and the closed space form a resonator having a predetermined resonance frequency.
