An electrical equipment including: an exterior having an opening portion; a circuit board provided to an inside of the exterior and configured to be connected to a commercial power source; a varistor mounted on the circuit board; and a line filter mounted on the circuit board, wherein the opening portion is formed in a predetermined direction orthogonal to electrodes of the varistor, and wherein the line filter is arranged between the varistor and the opening portion in the predetermined direction so as to prevent a range of a conical shape having a vertex at a center of the varistor, a height in the predetermined direction, and a predetermined solid angle θ from intersecting with the opening portion.
