PROBLEM TO BE SOLVED: To provide a laminate cell manufacturing device capable of manufacturing a laminate cell of substantially causing no irregularity of a position, without flawing the laminate cell in cutoff time, by laminating a first electrode foil strip and a second electrode foil strip with excellent positional accuracy.SOLUTION: A laminate cell manufacturing device comprises a cutting mechanism for forming as an electrode foil pair strip laminated one by one of a first electrode foil strip and a second electrode foil strip by cutting a first electrode foil cloth roll of arranging the second electrode foil strip in the width direction and a pedestal proximally arranged to the cutting mechanism and laminating the electrode foil pair strip, and the cutting mechanism is constituted of an upper side rotary blade arranged on the carrying passage upper side of a first electrode foil carrying mechanism for carrying the first electrode foil cloth roll and a lower side rotary blade arranged on the carrying passage lower side, and a rotary shaft of the upper side rotary blade and the lower side rotary blade is slantingly arranged in the vertical direction to the carrying direction of the first electrode foil carrying mechanism, and an outer peripheral surface of the upper side rotary blade and the lower side rotary blade slantingly crosses by an inclination or more of the rotary shaft with its side surface.SELECTED DRAWING: Figure 1 【課題】第１電極箔短冊と第２電極箔短冊とを位置精度良く積層させて、位置の不揃いがほとんどない積層電池を製造することができ、さらに切断時に積層電池に傷が付くことがない積層電池製造装置を提供すること。【解決手段】第２電極箔短冊が配置された第１電極箔反物を幅方向に切断することで、第１電極箔短冊と第２電極箔短冊とが１枚ずつ積層された電極箔ペア短冊とする切断機構と、切断機構とは近接して配置され、電極箔ペア短冊が積層される台座と、を備え、切断機構は、第１電極箔反物を搬送する第１電極箔搬送機構の搬送路上側に配置された上側回転刃と、搬送路下側に配置された下側回転刃とから構成され、上側回転刃および下側回転刃の回転軸は、第１電極箔搬送機構の搬送方向に対して上下方向に傾いて配置されるとともに、上側回転刃および下側回転刃の外周面は、その側面に対して回転軸の傾き以上に傾斜して交差していることを特徴とする。【選択図】図１
