The present invention provides a thin-walled, high-rigidity photography platform for breast photography. Accompanied by this, it is provided a mammography stage for which the X-ray transmittance can be improved due to thinning and the radiation exposure dose of a subject can be reduced.A photography platform for a breast photography device is a photography platform for a breast photography device supported by a breast photography device body in a cantilever state. At least an X-ray irradiation surface of the photography platform is formed of the carbon fiber composite material, and the carbon fiber composite material system is A unidirectional carbon fiber composite material containing unidirectionally drawn carbon fibers and a matrix resin.本發明係提供薄壁、高剛性的乳房攝影用攝影台。伴隨之,提供X光透射性得以因薄壁化而提升,且可降低受檢者的輻射曝露劑量之乳房攝影用攝影台。一種乳房攝影裝置用攝影台,係以懸臂樑的狀態支持於乳房攝影裝置本體之乳房攝影裝置用攝影台,前述攝影台的至少X光照射面係以該碳纖維複合材料形成,前述碳纖維複合材料係包含含有經單向拉齊的碳纖維和基質樹脂之單向碳纖維複合材料。
