Abstract
A lens-fitted photo film unit of a waterproof type comprises a unit body covered with a case body and a lid member. A front window and a top window of the case body are made of transparent plastic. The lid member is also made of the transparent plastic. Methacrylate styrene resin is utilized as the transparent plastic, which is used for a taking lens, a viewfinder lens, and an underwater case constituted of the case body and the lid member. This transparent plastic is hardly clouded even if cosmetics of suntan lotion and so forth adhere thereto. Moreover, a poisonous gas causing photographic-film fog is prevented from rising so that photographic properties are not damaged.
