PROBLEM TO BE SOLVED: To provide a vehicular air conditioner with improved mountability to a vehicle, while reducing an amount of sealed refrigerant. SOLUTION: By arranging a liquid tank 3 in a position away from a condenser 2, a wind receiving area of the condenser 2 is secured widely, heat dissipation performance of the condenser 2 can be improved, and refrigerating performance of a refrigerating cycle can be improved. Since a turbulence structure is provided in a branch part 23 of a branching passage 22 in a structure connected to the liquid tank 3 above the upward facing branching passage 22 of a midway part 21 of a refrigerant passage from the condenser 2 to an expansion valve 4, vapor phase refrigerant contained in liquid phase refrigerant passing through the branch part 23 easily floats up to the upper liquid tank 3 through the branching passage 22. In other words, an amount of vapor phase refrigerant not floating up to the liquid tank 3 from the branch part 23, and washed away to piping 8 of a subcooling condenser (a double tube 10) in a downstream side as it can be reduced, and there is an advantage of being able to stably supercool the refrigerant in the subcooling condenser 10.
