PURPOSE:To enable a filter case, which suppresses unnecessary discharge with high reliability, to be simply and easily made, and enable unnecessary discharge to be securely suppressed by making the said filter case by folding the four sides of a bottom surface, and folding the four corners of side surfaces before they are fixed by caulking. CONSTITUTION:A filter case, which suppresses unnecessary discharge and into which a capacitor and a choke coil are installed, is formed by folding folded parts 5 of the four sides of a bottom wall, folding folded parts 7 of the four corners of side walls, and fixing the parts 7 by caulking. By the means mentioned above, a filter case with a high reliability can be exceptionally simply made, and the suppression of unneedful high harmonic discharge can be secured. |
