[Problem to be Solved] To provide a porous plate for medical use which can suppress bending along a row direction and, even if a local crack occurs, can inhibit the crack from growing and leading to a fracture [Solution] One aspect of the present invention is a porous plate for medical use which is a thin-plate substrate 61 provided with a pore perforation section 63 having a plurality of pores 62 perforated therein and a frame section 64 surrounding the pore perforation section. In this porous plate 60, the pore perforation section 63 has crosspieces 65 which extend lengthwise and crosswise in continuity with the frame section 64 and partition the pore perforation section into a plurality of parts, and a plurality of pore perforation cells 66 each surrounded by the crosspieces 65. The pores 62 perforated in the pore perforation cells 66 have a pore diameter calculated as an equivalent circular pore diameter of 1 to 50 µm, and the center-to-center distance between the adjacent pores is 2 to 200 µm.
