摘要：
An example of the present invention is provided with porous sheets 11, 21 each formed by layering a porous base material including a polyolefin and a heat-resistant porous layer including a heat-resistant resin. The porous sheets 11, 21, respectively, are connected at connecting regions 15a and 15b, 25a and 25b, respectively, which have been formed by thermal fusion of the heat-resistant porous layers facing each other by folding the sheets. Furthermore, the porous sheets 11, 21 are additionally connected at a connecting region 27 that has been formed by thermal fusion.
