Disclosed herein is a system for preparing a microporous laminated sheet, which allows a stable breath ability of microporous film to be maintained while making an adhesion of the microporous film excellent. Also, a method of preparing the microporous laminated sheet using the system and a microporous laminated sheet prepared thereby are disclosed. The preparing system includes an adhesive-applying section serving to apply an adhesive in the linear or lattice shape on the microporous film. Also, the microporous laminated sheet includes a microporous film formed from a resin composition comprising 30 to 70% by weight of a polyolefin resin, 1 to 70% by weight of alpha-olefin copolymer, and 20 to 70% by weight of an inorganic filler; a polypropylene reinforcement bonded to one side of the microporous film and serving to reinforce the microporous film; and an adhesive interposed between the microporous film and the reinforcement in a linear or lattice shape and serving to bond the microporous film and the reinforcement to each other.
