PROBLEM TO BE SOLVED: To provide a heat exchanger, achieving compactness under the high-temperature and high-pressure conditions, and having high performance and excellent structural soundness. SOLUTION: This plate stacked type heat exchanger has such compactness that the exchange calorie per unit volume is 10 MWt/m<SP>3</SP>or more. The heat exchanger is used under such high-temperature and high-pressure condition that a differential pressure between the primary system fluid and the secondary system fluid ranges from 4 to 7 MPa, and the highest working temperature ranges from 500 to 900°C. In the heat exchanger, the board thickness of a metal plate is 0.3 times or more as large as the passage equivalent diameter, and the inter-passage pitch along the board thickness direction of the metal plate is 0.5 times as large as the passage equivalent diameter.
