Claim Text:
1. A reactor comprising: a reaction passage that is a fine flow passage that allows a plurality of different raw material fluids to react with each other while the raw material fluids are being circulated therethrough; and a temperature control passage that is a fine flow passage that allows a temperature control fluid to be circulated therethrough, the temperature control fluid being used for controlling temperature of the raw material fluids flowing through the reaction passage, wherein the reaction passage includes: a plurality of supply passage parts to which the plurality of the different raw material fluids are introduced, respectively; a confluence part that is connected to downstream-side ends of the plurality of the supply passage parts and allows the plurality of the raw material fluids inflowing from the plurality of the supply passage parts to join; and a reaction passage part that is connected to a downstream side of the confluence part and allows the plurality of the raw material fluids inflowing from the confluence part to react with each other while being circulated therethrough, wherein the temperature control passage includes: a plurality of first temperature control passage parts each of which has a part that extends along at least a particular range from the confluence part to the reaction passage part on the downstream side, in the reaction passage; and a second temperature control passage part that is connected to downstream-side ends of the plurality of the first temperature control passage parts, the number of the second temperature control passage part being smaller than the number of the plurality of the first temperature control passage parts, and wherein an area of a cross section of the second temperature control passage part in a direction perpendicular to a flow direction of the temperature control fluid in the second temperature control passage part is greater than an area of a cross section of each first temperature control passage part in a direction perpendicular to a flow direction of the temperature control fluid in the first temperature control passage part.
