To provide an electronic component manufacturing device capable of enlarging a length of a peeling start point.SOLUTION: A cut blade 4 includes a first side 4a, a second side 4b which is connected with the first side 4a at an acute angle, and a third side 4c which is connected with the second side 4b at an obtuse angle. When the cut blade 4 falls down and a blade tip 4E is brought into contact with a long green sheet 7, a first side initial angle XA which is an angle formed from a principal surface of a cut stage 3 and the first side 4a is 90° or larger and 91° or smaller. While the cut blade 4 further falls down and the cut blade 4 cuts the long green sheet 7 into rectangular green sheets 8, a first side cut-time angle XB which is an angle formed from the principal surface of the cut stage 3 and the first side 4a becomes larger than the first side initial angle XA.SELECTED DRAWING: Figure 4 【課題】 剥離起点の長さを大きくすることができる電子部品製造装置を提供する。【解決手段】 カット刃４は、第１辺４ａと、第１辺４ａと鋭角に接続された第２辺４ｂと、第２辺４ｂと鈍角に接続された第３辺４ｃとを有し、カット刃４が下降し、刃先４Ｅが長尺状のグリーンシート７に接した時に、カットステージ３の主面と第１辺４ａとがなす角度である第１辺初期角度ＸＡが、９０°以上、９１°以下であり、カット刃４が更に下降し、カット刃４が長尺状のグリーンシート７を矩形状のグリーンシート８にカットしている時に、カットステージ３の主面と第１辺４ａとがなす角度である第１辺カット時角度ＸＢが、第１辺初期角度ＸＡよりも大きくなるようにする。【選択図】 図４
