摘要： A monolith-type reactor includes a porous support body, a plurality of first cells through which a raw material gas flows, a plurality of second cells through which the sweep gas flows, separation membranes, and a catalyst. The first cells pass through the porous support body in a first direction. The second cells extend in the porous support body in the first direction. The separate membranes are respectively formed on inner peripheral surfaces of the first cells and permeable to a product of the conversion reaction. The catalyst is arranged inside the separation membranes, and promotes the conversion reaction. In a cross section taken along a second direction perpendicular to the first direction, the average cross-sectional area of the first cells is larger than the average cross-sectional area of the second cells.
