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. One aspect of the present invention is a porous plate for medical use which is a thin-plate substrate provided with a pore perforation section having a plurality of pores perforated therein and a frame section surrounding the pore perforation section. In this porous plate, the pore perforation section has crosspieces which extend lengthwise and crosswise in continuity with the frame section and partition the pore perforation section into a plurality of parts, and a plurality of pore perforation cells each surrounded by the crosspieces. The pores perforated in the pore perforation cells have a pore diameter calculated as an equivalent circular pore diameter of 1 to 50 &#x3bc;m, and the center-to-center distance between the adjacent pores is 2 to 200 &#x3bc;m.
