A ventilation housing includes a housing and ventilation component. A housing tubular projecting part has a communicating hole between housing inner and outer spaces. The ventilation component has: an attachment member over the projecting part with a contacting inner surface; an attachment member supported ventilation body covering a hole end portion between the inner and outer spaces; and a covering member including peripheral and top parts over the attachment member. At least one ventilation path connects the ventilation body and the outer space. A first contact part between an attachment member outer surface outermost protruding portion and covering member peripheral part inner surface is closer to the inner space than an end portion on the outer space side in a second contact part being a contact portion between the housing projecting part outer surface and the attachment member inner surface.
