ング方法である。<Means for Solving the Problems> This invention was made to solve the problems of the conventional method as described above, and it involves pasting a plastic film and a nonwoven fabric with fibers flowing in the length direction. Then, the adhesive layers of two masking tapes each having an adhesive layer on the non-woven fabric surface are placed facing each other, and a cylindrical capacitor element is placed between them at right angles to the length direction of the tapes and slightly away from the end surface of the tapes. The entire outer surface of the capacitor element is completely covered with masking tape so as to be on the inside of the capacitor element, forming a capacitor element chain, and after spraying metal on both ends of the capacitor element chain, two pieces of masking tape are applied. This is a method of masking the sides of a capacitor element by peeling off the tape.

行なえる。<Effects of the Invention> As described above, the masking tape used in the masking method of the present invention is a bonded product of a plastic film and a nonwoven fabric with fibers flowing in the length direction. When the tape is wrapped around a capacitor element, even if the tape is applied to the element with a slight bend, the elasticity of the non-woven fabric will prevent a gap from forming between the tape and the element. Because it is perpendicular to the length direction and located slightly inside the end face of the tape, during metal spraying, the metal does not wrap around unnecessary parts other than both end faces of the capacitor element, making continuous work possible. can be done.
又、不織布の繊維が長手方向に多く走つている
ため、破れとか裂けの発生が全くない。 Furthermore, since many fibers of the nonwoven fabric run in the longitudinal direction, there is no occurrence of tearing or tearing.
