Abstract: A reel body of a double bearing reel according to the invention has a left side plate that has a circular shape as viewed laterally and is situated further from a handle. An outer diameter of a right frame body that serves as another side plate situated closer to the handle is larger than an outer diameter of the left side plate. The reel body includes one or more connecting members that connect the left side plate and the right frame body. Among the connecting members, at least the connecting member that connects the side plates in front of the spool has a planar outer surface facing away from the spool and a curved inner surface facing the spool. The inner surface is formed to be convex outward, and the connecting member is connected to the left side plate through an arc-like bowed portion.

Abstract: A proton-conducting film suitable for use as an electrolyte in a small fuel cell and a method of manufacturing the proton-conducting film. A proton-conductive film contains at least silicon, and has a plurality of pores three-dimensionally oriented with regularity. The pore diameter is smaller than 5 nm, and the film thickness is within the range from 100 to 10000 nm. The film may be manufactured by preparing a solution for making the film containing at least silicon, adding a surfactant to the solution, attaching the solution in film form to a surface of a substrate, and heating the film at 300 to 800° C. to remove the surfactant and to cause glass transition.
