    • PROBLEM TO BE SOLVED: To provide a composite sheet body in which falling-off of particulates accompanied with pulverization of a hydrogen storage alloy, and which is easily deformable, and provide a manufacturing method in which the composite sheet body can be manufactured by a simple process. SOLUTION: Fiber materials such as pulp that become raw materials of paper are dispersed into a solution together with hydrogen storage alloy particulates 3, and by a similar technique as that of tamezuki (accumulated papermaking), this is poured into a wire cloth (papermaking net) to form this into a sheet-form. When the formed sheet body is dried, a fiber structure 2 in which the fiber materials have been entangled mutually and bonded to each other is formed, and the hydrogen storage alloy particulates 3 are dispersed and retained in the inside. Numerous gaps are formed among the fiber materials in the fiber structure 2 that has excellent gas permeability. Furthermore, the hydrogen storage alloy particulates are easily deformable similar to the paper, and they are locked to the gaps among the fiber materials so that their falling-off is prevented.
