One embodiment of the present invention is a medical multi-aperture plate in which a through-hole forming portion 63 having a plurality of through-holes 62 formed therein and a frame portion 64 surrounding the through-hole forming portion are provided on a thin plate-is there. In this multi-aperture plate 60, the through hole forming portion 63 has a crosspiece portion 65 connected to the frame portion 64 to extend in the front-rear direction and the left-right direction and to partition the through hole forming portion into a plurality of portions, a plurality of through hole forming cells 66 surrounded by the crosspiece portion 65 . The through hole 62 formed in the through hole forming cell 66 has a hole diameter of 1 to 50 m in terms of a circular hole and a distance between the centers of adjacent through holes of 2 to 200 m.本発明の一つの態様は、薄板状の基材61に、複数の貫通孔62が形成された貫通孔形成部63と貫通孔形成部を囲む枠部64とが設けられた医療用多孔プレートである。この多孔プレート60では、貫通孔形成部63は、枠部64と繋がって前後左右に延び貫通孔形成部を複数に仕切る桟部65と、桟部65に囲まれた複数の貫通孔形成セル66とを有して構成される。貫通孔形成セル66に形成された貫通孔62は、円孔に換算した孔径が1~50μmであり、隣接する貫通孔の中心間距離が2~200μmで構成される。
