Patent ID: 7854776

Claim:
A reactor comprising: a plurality of substrates including (i) a pair of a top substrate and a bottom substrate having provided therein recessed portions for forming closely sealed regions and (ii) a plurality of intermediate substrates having provided therein openings that communicate with each other; a reactor main body portion comprising the plurality of intermediate substrates, which are formed to be laminated and joined with each other; and an envelope portion which houses the reactor main body portion therein except for one end side of the reactor main body portion via a closely sealed space formed by sandwiching the plurality of laminated intermediate substrates between the top substrate and the bottom substrate, which are laminated and joined with the plurality of laminated intermediate substrates, and by communicating the openings and the recessed portions for forming the closely sealed regions of the plurality of substrates; wherein the envelope portion includes a support portion which supports the reactor main body portion via the one end side of the reactor main body portion; wherein an inside of the closely sealed space is set at an air pressure that is lower than an atmospheric pressure; wherein the reactor main body portion includes at the one end side a plurality of flow channels which supply a reactant and discharge a reacted product, the envelope portion includes on an outer face a supply/discharge portion formed of ends of the plurality of flow channels, and the plurality of flow channels are provided at the support portion; wherein the reactor main body portion includes (i) a first reaction unit set at a first temperature, (ii) a second reaction unit set at a second temperature that is lower than the first temperature, and (iii) a connection portion having a plurality of flow channels to communicate between the first reaction unit and the second reaction unit; and wherein the one end side of the reactor main body portion is provided at an end of a side of the reactor main body portion at which the second reaction unit is provided.
