<p>[PROBLEMS] A disposable cell counting board in which a space formed by a counting board body and an upper plate is fixed in advance, and which does not require assembling by a cell counting worker, and can be mass-produced at low costs. [MEANS FOR SOLVING PROBLEMS] The cell counting board comprises a body (10A) and a cover plate (30) mounted to the body (10A). The body (10A) has flat lands (12, 13) positioned lower a preset dimension than the upper surface of a portion (11), counting units (14, 15) provided on the lands (12, 13) respectively, and four protrusions (20) provided close to the lands (12, 13) to position and fix the cover plate (30) on the lands (12, 13). The cover plate (30) has fitting holes (32) formed at positions matching the protrusions (20). When the cover plate (30) is mounted on the body (10A) by fitting the protrusions (20) in the fitting holes (32), a space (40) having a specified size (0.1mm) is formed between the upper surfaces of the lands (12, 13) and the lower surface of the cover plate (30).</p> |
