To provide an electric connection box and a wire harness capable of improving waterproofness.SOLUTION: An electric connection box 1 includes a frame 3 for housing an electronic component 100 and a lower cover 5 located below the frame 3 and closing a lower opening 3b. In the frame 3, a double wall having a first outer wall 31 and a first inner wall 32 is formed along the lower opening 3b. The lower cover 5 has a second outer wall 51 positioned between the first outer wall 31 and the first inner wall 32 in an installed state, and a second inner wall 52 formed along the second outer wall 51 inside the second outer wall 51. The first inner wall 32 has a body portion 32A in which a lower end portion 32a is located between the second outer wall 51 and the second inner wall 52 in the installed state, and a bulging portion 32B that bulges from an opposing surface 31Aa opposed to the first outer wall 31 of the body portion 32A toward the first outer wall 31. The bulging portion 32B is formed so as to be oppose to the second outer wall 51 in a vertical direction in the installed state and overlap when viewed from the vertical direction.SELECTED DRAWING: Figure 4 【課題】防水性を向上させることができる電気接続箱およびワイヤハーネスを提供する。【解決手段】電気接続箱１は、電子部品１００を収容するフレーム３と、フレーム３の下方側に位置し、下方側開口部３ｂを閉塞するロアカバー５とを備える。フレーム３は、第１外壁３１および第１内壁３２を有する二重壁が下方側開口部３ｂに沿って形成される。ロアカバー５は、設置状態で第１外壁３１と第１内壁３２との間に位置する第２外壁５１と、第２外壁５１の内側において、第２外壁５１に沿って形成される第２内壁５２とを有する。第１内壁３２は、設置状態で第２外壁５１と第２内壁５２との間に下方側端部３２ａが位置する本体部３２Ａと、本体部３２Ａの第１外壁３１と対向する対向面３１Ａａから第１外壁３１に向けて膨出する膨出部３２Ｂとを有する。膨出部３２Ｂは、設置状態で第２外壁５１に対して上下方向に対向し、上下方向から視て重なるように形成される。【選択図】図４
