PROBLEM TO BE SOLVED: To achieve cost reduction by a simple structure, exhibit a filter function during the operation of air conditioning and supplement heating and cooling the inside of a cabin only for a predetermined time by effectively using latent heat after the supply of a heat exchange medium to a heat exchanger is stopped. SOLUTION: In an air-conditioning unit 1A, an evaporator 5, an air mix door 6 and a heater core 7 are sequentially arranged from an upstream air blower 3 side toward a downstream air outlet 14, 15, 16, 17 side in an air-conditioning case 2, and a warm air passage 8 passing through the evaporator 5 and the heater core 7, a cold air bypass passage 9 passing through the evaporator 5 and bypassing the heater core 7 and an air mix chamber 10 where warm air and cold air are merged are formed. In the wake flow side passage of the heat exchanger of at least one of the evaporator 5 and the heater core 7, a heat storage filter 18 is set in an arrangement orthogonal to an air flow.
