PROBLEM TO BE SOLVED: To provide a detection cell having a long working length with which light is transmitted through a liquid sample, and shielding an excessive beam unnecessary for detection, and a manufacturing method of the detection cell for manufacturing the detection cell highly accurately. SOLUTION: An approximately linear detection passage 12 is formed on a substrate 11, and a sample introduction passage 13 for introducing the liquid sample is formed on one end of the detection passage 12, and a sample discharge passage for discharging the liquid sample is formed on the other end, respectively on positions except in the linear direction of the detection passage 12. A pinhole formation groove 16 for entrance/exit of a beam is formed on the substrate side face 15 in the linear direction of the detection passage 12, and an upper plate 17 is laminated on the upper surface of the substrate 11, and the substrate side face 15 on which the pinhole formation groove 16 is formed is covered with a shielding film 18 excepting the pinhole formation groove 16.
