<P>PROBLEM TO BE SOLVED: To provide connecting tubes for a distributor which suppresses a refrigerant sound while improving distribution characteristics. Ž<P>SOLUTION: In the connecting tubes 6a, 6b, 6c of the distributor for connecting flow passages of an indoor heat exchanger (not shown in figures) composed of a plurality of refrigerant flow passages and the collision-type distributor (not shown in figures) for distributing a refrigerant, tips 7 of the connecting tubes 6a, 6b, 6c at the indoor heat exchanger side are throttled to have thin diameters. This can decrease the flowing speed of the refrigerant and rectify the refrigerant so as to suppress the generation of the refrigerant sounds from the connecting tubes 6a, 6b, 6c in the indoor heat exchanger.
