PROBLEM TO BE SOLVED: To provide a reaction cell for a biochemical automatic analysis device with high analysis efficiency, preventing occurrence of weld in a light transmission part, reducing scattering of transmitted light, and having stable transmissivity.SOLUTION: In a bottomed reaction cell where an opening part is formed at one end, the pipe wall of the reaction cell has a pair of wall surfaces facing to each other, and two side wall surfaces connected to each of the pair of wall surfaces through corner parts. The wall thickness of the pair of wall surfaces is made thicker than the thickness of the corner part and is made uniform over the whole wall surface, or in a case where there is a maximum value at a part of each wall thickness, the wall thickness is monotonously reduced from the position of the maximum value to the corner part. |
