PROBLEM TO BE SOLVED: To provide a heat source unit including a refrigerating cycle in which a refrigerant uniformly flows to a plurality of heat exchangers without generating deflection of refrigerant flow in a branch pipe due to difference in openings of a plurality of expansion valves, to exercise its ability. SOLUTION: This heat source unit is constituted by connecting a compressor, the plurality of heat exchangers and the plurality of expansion valves by refrigerant pipes, and includes an expansion valve connection pipe to which valve bodies of the plurality of expansion valves are connected in parallel roughly in the vertical direction, and which is roughly horizontally disposed, a cross pipe connected to the expansion valve connection pipe through a first connection port, a collision pipe connected to a second connection port at a side opposite to the first connection port, and the branch pipe horizontally connected to a third connection port and a forth connection port of the cross pipe for dividing the refrigerant to the plurality of heat exchangers.
