    摘要： An acylated cellulose film having a high optical isotropy and uniformity is produced by dissolving an acylated cellulose in a solvent substantially free from water and including, as a principal component, 1,3-dioxolane in a ratio in weight of the acylated cellulose to the solvent of 10/250 to 10/15; spreading the acylated cellulose solution on a film-forming surface of a support; and drying, for example, initially drying the spread solution layer on film-forming surface so as to reduce the content of the residual solvent in the resultant film to 5 to 30% by weight; removing the resultant residual solvent-containing film from the film-forming surface; and finally drying the removed film, while allowing the film to shrink in the transversal direction thereof, at a drying temperature controlled continuously or intermittently to a level satisfying the relationship (I): (Tg'-50.degree. C.).ltoreq.T.ltoreq.(Tg'+20.degree. C.) (I), wherein T is the drying temperature (.degree.C.) and Tg' is a glass transition temperature (.degree.C.) of the solvent-containing film, the temperature Tg' varying in response to the solvent content in the film.

    摘要： An electric storage device, includes an electrode assembly that includes a positive electrode and a negative electrode each including a current collector provided with an active material layer on a surface thereof except one end, the positive electrode and the negative electrode being wound or stacked with a separator interposed therebetween, wherein one end of one of the positive electrode and the negative electrode on at least one side of the electrode assembly protrudes, as active material layer-unformed parts, from a side end of the remaining electrode different in polarity; a case for housing the electrode assembly with the protruding direction of the one end oriented sideways; and an electrolytic solution being reserved in the case, wherein the active material layer-unformed parts include electrolytic solution-sucking-up layers that are porous and are formed along a direction orthogonal to the protruding direction of the one end.
