A hollow fiber bundle that is formed by arranging a plurality of porous hollow fiber membranes 8 in one direction a heat exchange pipe bundle that is formed by arranging and laminating a plurality of heat exchange pipes 9 in one direction crossing the hollow fiber membranes and is apposed with the hollow fiber bundle and a potting material 10 that is filled in a region including both end parts of the hollow fiber membranes and the heat exchange pipes and forms a blood channel extending across the hollow fiber membranes and the heat exchange pipes are provided. The housing includes: blood ports 3a, 3b that face both ends of the blood channel gas headers 4a, 4b that form gas ports 5a, 5b facing both ends of the hollow fiber bundle and heat exchange headers 6a, 6b that form heat exchange liquid ports 7a, 7b facing both ends of the heat exchange pipe bundle. The blood flows through the blood channel and an oxygen-containing gas flows through a bore of the hollow fiber membrane so as to perform the gas exchange, and the heat exchange liquid flows through a bore of the heat exchange pipe so as to perform the heat exchange. A hollow fiber membrane-type artificial lung, in which the heat exchange part is apposed with the gas exchange part without unnecessarily increasing a priming volume, can be structured.
