A method for manufacturing a laminated stator core using a lateral side of a magnetic strip as a side of a core sheet (15, 16), the core sheet having a rectangular shape with a vertical width of (a + β / 2 - α / 2) and a lateral width of "b", the core sheet having a round shaped rotor space formed eccentrically in lateral and vertical directions to a center of the core sheet (15, 16), the method characterized by having the steps of: Step 1 of forming the rotor spaces, the rotor spaces adjacent in a feed direction of the strip having a distance of "b" between the centers thereof, the rotor spaces in the core sheets (15, 16) at the end in the width direction of the strip having the centers located (a - a)/2 inward from the side edge of the core sheets (15, 16); Step 2 of punching out slots (39, 40, 41) in the strip having the rotor spaces, the slots (39, 40, 41) formed with respect to the center of the rotor space, thereby forming magnetic pole pieces (37, 38) in the inner part of the core sheet (15, 16) and circular-arc shaped locating portions at the corners of the core sheet (15, 16) axisymmetrically with respect to the center of the rotor space; and Step 3 of punching out the core sheet (15, 16) using a set of a punch and a die in a manner that axes of the punch and the die are aligned with the center of rotor space, each of the punch and the die having a vertical width of (a + β) and a lateral width of (b + γ); pressing the core sheet (15, 16) into the die; and laminating the core sheet (15, 16) inside the die with a position thereof adjusted using positioning walls fitting to the locating portions of the core sheet (15, 16); wherein the die rotates every core sheet (15, 16) or every set of the plural core sheets (15, 16) by 180 degrees prior to the lamination of the core sheets (15, 16) to form projections and recesses of 0.5- to 4-fold of the thickness of the core sheets (15, 16) along the sides of the laminated stator core, values of α, β, and γ being in the range of 0 < α < 0.05a, 0 < β < 0.05a and 0 < γ < 0.05b, respectively. Step 1 of forming the rotor spaces, the rotor spaces adjacent in a feed direction of the strip having a distance of "b" between the centers thereof, the rotor spaces in the core sheets (15, 16) at the end in the width direction of the strip having the centers located (a - a)/2 inward from the side edge of the core sheets (15, 16); Step 2 of punching out slots (39, 40, 41) in the strip having the rotor spaces, the slots (39, 40, 41) formed with respect to the center of the rotor space, thereby forming magnetic pole pieces (37, 38) in the inner part of the core sheet (15, 16) and circular-arc shaped locating portions at the corners of the core sheet (15, 16) axisymmetrically with respect to the center of the rotor space; and Step 3 of punching out the core sheet (15, 16) using a set of a punch and a die in a manner that axes of the punch and the die are aligned with the center of rotor space, each of the punch and the die having a vertical width of (a + β) and a lateral width of (b + γ); pressing the core sheet (15, 16) into the die; and laminating the core sheet (15, 16) inside the die with a position thereof adjusted using positioning walls fitting to the locating portions of the core sheet (15, 16);
