To provide a laminated core manufacturing apparatus and a method for manufacturing a rotating electric machine, capable of manufacturing a laminated core constituting a highly efficient rotating electric machine at low cost and with good productivity.SOLUTION: The laminated core manufacturing apparatus 100 includes a press machine 10 having a punch 13P and a die 13D for punching out a core piece 5P from a plate material 5 with the plate thickness direction W of the plate material 5 as the punching direction, and a plate material supply device 20 that feeds the plate material to the press machine with the plate thickness direction of the plate material perpendicular to the direction of gravity. The press machine 10 includes a guide 10G that aligns the core pieces 5P ejected from the die 13D in the punching direction by the punch 13P in the punched posture and stacks the core pieces 5P.SELECTED DRAWING: Figure 1 【課題】高効率な回転電機を構成する積層コアを、低コストかつ生産性良く製造できる積層コア製造装置および回転電機の製造方法を提供する。【解決手段】積層コア製造装置１００は、板材５から鉄心片５Ｐを板材５の板厚方向Ｗを打ち抜き方向として打ち抜くパンチ１３Ｐとダイ１３Ｄを備えるプレス機１０と、板材の板厚方向を、重力方向に対して垂直にして、板材を前プレス機に供給する板材供給装置２０を備え、プレス機１０は、ダイ１３Ｄ内からパンチ１３Ｐによる打ち抜き方向に排出される鉄心片５Ｐを、打ち抜いた姿勢のまま整列して鉄心片５Ｐ群を積層させるガイド１０Ｇを備える。【選択図】図１
