To provide an electric connection box that comprises an electric wire lead-out cylinder part which eliminates complicated tape winding work to lead an electric wire out compactly.SOLUTION: An electric connection box 1 comprises: a main body-side half-cylinder part 11 and a lower cover-side half-cylinder 21 formed in a half-split shape respectively at a case body 10 and a lower cover 20 so as to define an electric wire lead-out cylinder part 3 leading an electric wire bundle 2, led out of the case body 10, between the case body 10 and the lower cover 20 which are assembled; and an annular clamp member 30 which is fitted in the electric wire lead-out cylinder part 3. The annular clamp member 30 has: a first half-ring part 31 and a second half-ring part 35 formed in a half-split shape so as to keep the electric wire bundle 2 in an inserted state; seal members 51, 55 which are provided on inner peripheral surfaces of the first half-ring part 31 and second half-ring part 35 respectively to be in close contact with an outer periphery of the electric wire bundle 2; and an anchor part 38 which is protruded on an outer peripheral surface of the second half-ring part 35 to be fitted in an anchor fixation hole 13 formed in the main body-side half-cylinder part 11.SELECTED DRAWING: Figure 3 【課題】煩雑なテープ巻き作業が不要になり、コンパクトに電線束を導出することができる電線導出筒部を備えた電気接続箱を提供する。【解決手段】電気接続箱１は、組み付けられたケース本体１０とロアカバー２０との間に、ケース本体１０から引き出される電線束２を導出する電線導出筒部３を画成するためケース本体１０及びロアカバー２０にそれぞれ半割状に形成された本体側半筒部１１及びロアカバー側半筒部２１と、電線導出筒部３内に嵌装される環状クランプ部材３０と、を備える。環状クランプ部材３０は、電線束２を挿通状態に保持するため半割状に形成された第１半環部３１及び第２半環部３５と、電線束２の外周に弾性的に密着するため第１半環部３１及び第２半環部３５の内周面にそれぞれ設けられたシール部材５１，５５と、本体側半筒部１１に形成されたアンカー固定穴１３に嵌挿するため第２半環部３５の外周面に突設されたアンカー部３８と、を有する。【選択図】図３
