Printed surface 202b and 204b in black color are formed on a second plate 2 and a fourth plate 4. The printed surface 202b covers almost the entire surface of the second plate 2 except for an area smaller than a diameter of a through-portion 71 of a third plate 3. A predetermined amount of reagent is applied to the part. The fourth plate 4 is configured in a similar manner to the second plate 2. The printed surfaces allows measurement with transmitted light blocked in the smallest diameter during measurement. This prevents inaccurate measurement due to position misalignment. |
