Reaction device, heat-insulating container, fuel cell device, and electronic apparatus

摘要

Disclosed is a reaction device that includes a reaction device main body that includes a first reaction unit and a second reaction unit, a container to house the reaction device main body and a first region that corresponds to at least the first reaction unit and a second region that corresponds to the second reaction unit, the first and second regions being provided to the container or internal side of the container. The first reaction unit is set to a temperature higher than that of the second reaction unit, and the first region has a higher reflectivity than that of the second region, with respect to a heat ray that is radiated from the reaction device main body.
