PROBLEM TO BE SOLVED: To provide an air-conditioning unit capable of providing air flow with desired temperature at individual air outlets, and keeping a space condition remarkably low, hardly using an additional insert. SOLUTION: The vehicular air-conditioning unit has a casing (4) equipped with at least three air outlets (7, 8, 9), is provided with an air cooling means (1) and an air heating means (2), and is provided with at least one heating heat exchanger (2) as the air heating means. The heating heat exchanger has at least one cold air passage (12, 13) at its vertically extended part. One cold air passage is arranged between two heating paths (10, 11). A steamer (1) is provided as the air cooling means. The heating heat exchanger is arranged at a downstream side of the steamer viewed in the air flow (3) direction. Accordingly, temperature-layered air flow is formed after the heating heat exchanger. Layers of the layered air flow are entirely or partially directly assigned to the outlets.
