摘要：
Provided is a laminated porous film having excellent shutdown characteristics and breakdown characteristics, good tearing strength and dimensional stability, and B activity. The laminated porous film comprises layer A, the main component of which is a polypropylene resin, and layer B which contains a polyethylene resin, and the ratio of the rearing strength (HMD) in the machine direction (MD) of the laminated porous film and the tearing strength (HTD) in the transverse direction (TD) of the laminated porous film with respect to the machine direction (HMD) (HTD) is 0.08 to 2.0.
