PROBLEM TO BE SOLVED: To reduce the surface exposed filler area with good adhesion between resin and filler, thereby minimizing the reaction between filler and acid gas, and to improve anti-fouling property without adding processes and increasing costs. Provide excellent resin insulation. A resin insulator composed of at least two materials of a resin and a filler, wherein a blending ratio of the filler is 50 to 75 parts by mass in 100 parts by mass of the whole resin composition, A filler having a particle size of 0.1 μm or less is contained in 0.006 to 0.03 parts by mass in 100 parts by mass of the whole filler, and a filler having a particle size of 11 to 30 μm is contained in 55 to 85 parts by mass in 100 parts by mass of the whole filler. .
