ータ。A pair of pieces with a roughly U-shaped cross section are brought together to form a flat refrigerant flow path in the intermediate part of the hollow part, and an inlet-side refrigerant reservoir and an outlet-side refrigerant reservoir at both ends of the hollow part, respectively. In a stacked evaporator, a stacked evaporator is provided with a diffusion means for distributing and distributing refrigerant in the refrigerant flow path of the flow path unit, in which a large number of flow path hurats and fins are connected alternately and adjacently, and an intermediate body of each of the pieces is provided. The wall to be formed is bulged in the direction of the hollow part to form a large number of elongated bead parts, each bead part being inclined with respect to the longitudinal direction of the refrigerant flow path, and a pair of pieces facing each other in a mid-aligned state. A laminated evaporator characterized in that the bead portions of the pieces are arranged so as to intersect and overlap, and the diffusion means is constituted by the bead portions.
