Claim Text:
1. A microreactor comprising: a reaction passage configured to flow a fluid as a reaction object; and a medium passage provided in parallel with the reaction passage and configured to flow a heat medium to exchange heat with the fluid in the reaction passage, wherein the reaction passage includes a catalyst layer provided at least on part of an inner wall of the reaction passage, the catalyst layer forming a high-activity region and a low-activity region in the reaction passage, a cross-sectional area of the medium passage adjacent to the high-activity region of the reaction passage is smaller than a cross-sectional area of the medium passage adjacent to the low-activity region of the reaction passage, any of heat generation and heat absorption associated with a reaction of the fluid in the high-activity region is larger than that in the low-activity region, a cross-sectional area of the high-activity region of the reaction passage is larger than a cross-sectional area of the low-activity region of the reaction passage, and a thickness of the catalyst layer in the high-activity region is larger than a thickness of the catalyst layer in the low-activity region.
