A laminated steel sheet for use in the manufacture of a two-piece can body that satisfies the following three formulae includes a polyester resin layer on at least one side of the steel sheet, the polyester resin layer containing 3% to 30% by volume of dispersed incompatible subphase resin having a glass transition point of 5° C. or less and a cross section aspect ratio of 0.5 or less: <?in-line-formulae description="In-line Formulae" end="lead"?>d<=r; 0.1<=d/R<=0.25; and 1.5<=h/(R-r)<=4,<?in-line-formulae description="In-line Formulae" end="tail"?> wherein R denotes the radius of a circular laminated steel sheet that has the same weight as that of the two-piece can body before processing, h denotes the height of the can body, r denotes the maximum radius of the can body, and d denotes the minimum radius of the can body. A high strain two-piece can, such as a two-piece aerosol can, formed of the laminated steel sheet is free from delamination and breakage of the resin layer.
