PROBLEM TO BE SOLVED: To improve waterproofness.SOLUTION: An electric connection box includes: a housing 10; and at least one electronic component 20 housed in the housing 10. The housing 10 includes: a housing chamber 11 in which an electronic component 20 is housed; a wire lead-out opening 12 which pulls out a wire We electrically connected to the electronic component 20 to the outside of the housing 10; and a wire routing space 13 for guiding the wire We pulled out from the housing chamber 11 to the wire lead-out opening 12. A wall body 10Dhaving an inner wall surface forming the wiring routing space 13 and forming an outer wall of the housing 10 includes a liquid drain hole 16 which is a through-hole communicating the wiring routing space 13 with the outside of the housing 10 and drains liquid immersed from the wire lead-out opening 12 toward the inner wall surface to the outside of the housing 10. The liquid drain hole 16 is formed in a first contact area FC of the inner wall surface, to which liquid immersed into the wire routing space 13 from the wire lead-out opening 12 first flows.SELECTED DRAWING: Figure 3
