PROBLEM TO BE SOLVED: To provide a method for producing a long thermosetting resin porous sheet not having a defective part causing breakage.SOLUTION: A method for producing a thermosetting resin porous sheet includes: a step for cutting a thermosetting resin so as to have a sheet shape having a prescribed thickness by bringing a cutting blade into contact with a thermosetting resin block, while rotating the cylindrical or circularly-columnar thermosetting resin block containing porogen around the axis of the cylinder or the axis of the circular column; and a step for removing porogen from the obtained thermosetting resin sheet to make it porous; wherein cutting is performed, while reciprocating the cutting blade approximately in parallel with a rotary shaft direction of the thermosetting resin block. |
