Abstract:
The heat exchanger including a plurality of fluid flow paths ( 401 ), ( 402 ), ( 403 ) arranged in a plurality of stages in a height direction, wherein a fluid inlet port ( 13 a ) and a fluid outlet port ( 13 b ) of the fluid flow path ( 403 ) located at a lowermost stage among the plurality of fluid flow paths ( 401 ), ( 402 ), ( 403 ) have larger flow path cross-sectional areas than a fluid inlet port ( 11 a ) and a fluid outlet port ( 11 b ) of the fluid flow path ( 401 ) located at an uppermost stage.

Claim (Index 4):
The heat exchanger according to  claim 1 , wherein\n the fluid flow path located at the lowermost stage among the plurality of fluid flow paths is disposed so as to protrude more inwardly of the case body than an upper-stage fluid flow path located at an upper stage than the fluid flow path located at the lowermost stage as viewed from an upstream side of the flow passage of the combustion exhaust gas.
