PROBLEM TO BE SOLVED: To provide an evaporator capable of further reducing nonuniformity of the temperature distribution. SOLUTION: A first path of an inlet side heat exchange part is formed as a lowering flow path, a second path is formed as a rising flow path, a third path is formed as a lowering flow path, and the first path of an outlet side heat exchange part is formed as a rising flow path, by arranging a communicating part in the other lower end part in the lateral direction for communicating the inlet side heat exchange part with the outlet side heat exchange part by arranging a refrigerant introducing port in one upper end part in the lateral direction. The number of heat exchange passages of the first path of the inlet side heat exchange part is made fewer than the number of heat exchange passages of any path of both heat exchange parts. The number of heat exchange passages of the second path of the inlet side heat exchange part is set to the number of heat exchange passages of more of the third path of the inlet side heat exchange part. The number of heat exchange passages of the first path of the outlet side heat exchange part is made fewer than the number of heat exchange passages of the third path of the inlet side heat exchange part.
