The utility model provides a clothes dryer which not only can prevent the damage of the connection part of a pipe in a heat pump as far as possible, but also can prevent the adverse effect caused by the action to the heat pump as far as possible. In the clothes dryer, an expanding part (80b) is arranged at the front end of a pipe (80) at the bearing side of a condenser (55). A pipe (83) at the insertion side connected with a compressor is inserted into the expanding part (80b), a reduction extending part (83b) with a smaller diameter is arranged at the front end part, and the reduction extending part (83b) is inserted into a pipe main body (80a) of the pipe (80). The joining part of the two pipes (80, 83) is soldered by brazing filler metal (84) to be connected. The front end part of the reduction extending part (83b) is inserted into the inside of an end plate (82) of the condenser (55).
