To provide a heat insulation structure of an electric component which can eliminate a need of a cooling device to improve heat radiation performance of the electric component and inhibit occupants from being affected by heat while inhibiting increase of manufacturing costs.SOLUTION: A heat insulation structure of an electric component 22 includes: a fixed bracket 21 having a placement surface 21a, on which the electric component 22 is placed, and installed on an upper surface of a floor panel 2 of a vehicle 1; a cover member 23; and a heat insulation bracket 41. The cover member 23 has a rib 23S, a rib 23T, and a rib 23U. The rib 23S is provided at a ceiling wall 23A and contacts with a right end part 41b as seen in a direction in which a ceiling wall 41A extends. The rib 23S is provided at a rear wall 23C facing a rear wall 41B and contacts with a right end part 41c of the rear wall 41B. The rib 23U is provided at the rear wall 23C and contacts with a lower end part 41a orthogonal to a direction in which the rear wall 41B extends.SELECTED DRAWING: Figure 6

    【課題】冷却装置を不要にして電装部品の放熱性能を向上でき、製造コストが増大することを抑制しつつ乗員が熱の影響を受けることを抑制できる電装部品の断熱構造を提供すること。【解決手段】電装部品22の断熱構造は、電装部品22が載置される載置面21aを有し、車両1のフロアパネル2の上面に設置される固定ブラケット21と、カバー部材23と、断熱ブラケット41とを備え、カバー部材23は、リブ23S、リブ23Tおよびリブ23Uを有する。リブ23Sは、天井壁23Aに設けられ、天井壁41Aの延びる方向の右端部41bに当接しており、リブ23Sは、後壁41Bに対向する後壁23Cに設けられ、後壁41Bの右端部41cに当接している。リブ23Uは、後壁23Cに設けられ、後壁41Bの延びる方向と直交する下端部41aに当接している。【選択図】図6
