A method of manufacturing a light control element including an extraction electrode portion includes the steps of obtaining a light control film including a first base material with a transparent electrode layer and a second base material with a transparent electrode layer arranged so that transparent electrode layers are opposed to each other, a liquid crystal light control layer sandwiched between the base materials with transparent electrode layers, and an extending portion extending in a direction perpendicular to a thickness direction; inserting peeling means between the base materials with transparent electrode layers in the extending portion, to thereby peel off one base material with a transparent electrode layer from the light control film and bending a peeled portion of the one base material with a transparent electrode layer outward, to snap the peeled portion. The one base material has a breakage bending diameter of from 0.1 mm to 5 mm.

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.
