PROBLEM TO BE SOLVED: To arrange a flat plate 11 on a first passage 7 of a refrigerant in order to fragment, agitate and equalize respective particles of the refrigerant of a gas-liquid two-phase state in a lamination type heat exchanger to be used as an evaporator, to easily and accurately pierce an outer diaphragm hole 14 by press molding and to improve pressure resistance of a space neighboring a refrigerant inlet part.SOLUTION: An aperture of a flat plate 11 is closed by a lid member 11a and the flat plate 11 and the lid member 11a are held between a first plate 5 and a second plate 6. An inside gap 17 is partially formed between an outer surface of the bottom of the flat plate 11 and the second plate 6, an inner diaphragm hole 18 is pierced into the inside gap 17, and an outer diaphragm hole 14 is formed on a joint part between the flat plate 11 and the lid member 11a. |
