PROBLEM TO BE SOLVED: To provide a penetration part structure for electrical wiring capable of protecting a seal member and the electrical wiring in a penetration part of a sealed container from heat.SOLUTION: A penetration part structure for electrical wiring includes: a cylindrical member 31 that is provided while penetrating a wall 21 of a sealed container 11; electrical wiring 41 which is passed through the cylindrical member 31 for electrically connecting the inside and the outside of the sealed container 11; a seal member 51 which is provided within the cylindrical member 31 and separates the inside and the outside of the sealed container 11; and a heat conductor 61 provided within the cylindrical member 31 closer to an internal part 13 of the sealed container 11 than the seal member 51. The heat conductor 61 is formed from a plurality of kinds of heat conductors 62 and 63 each having the heat conductivity being different from each other, and the plurality of kinds of heat conductors 62 and 63 are arranged side by side from the side of the internal part 13 off the sealed container to the side of an external part 14. |
