In a stacked evaporator in which a pair of core units 40 are formed by joining them with their inner surfaces facing each other, and a large number of core units are stacked to form a U-shaped refrigerant passage in each core unit, at least one of the plates is A bead 39 protruding toward the inner surface is formed at the other end of the plate 30, and a high-density portion 41 having a high density of the beads 39 is formed near the partition wall 32 at the other end of the plate 30. This is a stacked evaporator in which a low-density portion 42 having a lower bead density is formed on the end side of the high-density portion 41.
