An air-conditioning unit is configured to operate in an internal/external air two-layer mode. The air-conditioning unit includes an air-conditioning case defining a passage, a first heat exchanger, a second heat exchanger, an upstream partition and an intermediate partition. The upstream partition and the intermediate partition collectively partition the passage into a first passage through which internal air introduced from an internal air introducing port flows during the two-layer mode and a second passage through which external air introduced from an external air introducing port flows during the two-layer mode. The upstream partition is located upstream of the first heat exchanger and the intermediate partition is located between the first heat exchanger and the second heat exchanger. The intermediate partition is integrally formed with at least one of the first heat exchanger or the second heat exchanger.
