PROBLEM TO BE SOLVED: To improve the efficiency of removal of an evaporated metal near the cut surface of a capacitor element by laser beam and to make the removal dimension of the evaporated metal uniform. SOLUTION: In the manufacturing method of the stacked film capacitor comprising a process for removing an evaporated metal near a cut surface of the capacitor element by using laser beam by cutting a matrix capacitor element wherein a metallikon electrode 3 is formed on a laminated body formed by laminating a plurality of layers of both-side metallized films 1 with its both sides metallized and non-metallized films 2, or on a laminated body formed by laminating a plurality of layers of one-side metallized films with its one side metallized, an evaporation metal 8 is removed by moving an irradiation point 5 of a laser beam in the lamination direction 6 and the vertical direction 7 of the metallized film at the cut surface of the capacitor element. Thereby, it is possible to effectively remove the evaporated metal 8 near the cut surface of the capacitor element and to obtain a stacked film capacitor economically by saving the energy of an oscillation power source of the laser beam.
