To provide a vehicular air-conditioner capable of consistently blowing out air of very small volume.

The vehicular air-conditioner comprises a face blowout passage 61 and a foot blowout passage 62 for respectively distributing air to be blow out into a cabin from different outlets, a face mode door 63 and a foot mode door 64 for respectively opening/closing the face blowout passage 61 and the foot blowout passage 62 based on the blowout mode, a communication unit 65 for communicating the downstream side of the face mode door 63 out of the face blowout passage 61 with the foot blowout passage 62, and an upstream side structure 66 and a downstream side structure 67 which are formed in the vicinity of the communication unit 65, lead a part of air flowing from the upstream side of the foot blowout passage 62 to the downstream side of the face blowout passage 61 via the communication unit 65 and lead the air flowing from the upstream side of the face blowout passage 61 to the downstream side of the face blowout passage 61.
