In a refrigerant evaporator, a core has tubes that are arranged in a core width direction and at least in two rows including a first row and a second row. The first row is disposed downstream of the second row with respect to a flow direction of an external fluid. The tubes of the first row provide a refrigerant upward path and a refrigerant downward path. The core has a thickness equal to or less than 50 mm with respect to the flow direction of the external fluid, and a width equal to or greater than 220 mm with respect to the core width direction. The upward path is further than the downward path with respect to a refrigerant inlet disposed at an end of a first header tank, and has a width equal to or less than 95 mm with respect to the core width direction.
