A ventilation member and a ventilation member kit are provided that can extend the time until fogging will be produced in a housing and also can shorten the time until the produced fogging will be cleared up even when the interior of the housing has been fogged. A vented housing and a vented tank using them are also provided. A ventilation member includes: a first gas permeable membrane, a second gas permeable membrane, and an absorbing layer allowing a gas passing through an opening of a housing or a tank to permeate therethrough, with the ventilation member being fixed to the opening; a support body for supporting the first gas permeable membrane, the second gas permeable membrane, and the absorbing layer; and a first one-way valve disposed so as to cover the first gas permeable membrane. The first gas permeable membrane and the second gas permeable membrane are disposed in such a manner that the gas permeates through the gas permeable membranes independently of each other. The second gas permeable membrane and the absorbing layer are disposed in such a manner that the gas permeates through the second gas permeable membrane and the absorbing layer successively. The absorbing layer contains a water absorbent.

A gaseous component treatment sheet of the present invention has a gas-permeable base film and a particulate remover for removing a predetermined gaseous component, and the particulate remover is dispersed in the base film. A protective layer and/or an adhesive layer can be laminated further on the base film. Since the gaseous component treatment sheet is a sheet-like member including the base film for holding the particulate remover, the size and the shape can be adjusted easily.

Described are a fixing member formed of a sheet material equipped with a gas permeable portion covering a removing agent at a portion other than the peripheral portion of the sheet material, and an adhesion member disposed at the peripheral portion of the sheet material; an EL device using the fixing member; and a backing substrate of the EL device. Use of the fixing member contributes to a reduction in the manufacturing cost of an EL device.
