Abstract
An example of the present invention is provided with porous sheetseach formed by layering a porous base material including a polyolefin and a heat-resistant porous layer including a heat-resistant resin. The porous sheets, respectively, are connected at connecting regionsandand, respectively, which have been formed by thermal fusion of the heat-resistant porous layers facing each other by folding the sheets. Furthermore, the porous sheetsare additionally connected at a connecting regionthat has been formed by thermal fusion.
