PROBLEM TO BE SOLVED: To provide a sample measuring cell capable of easily changing optical path length, and a physical property measurement device provided with the sample measuring cell.SOLUTION: A sample measuring cell 1 of a physical property measurement device 100 measures a secondary electromagnetic wave 4b obtained when a primary electromagnetic wave 4a irradiated from a light source 4 transmits a sample including a measuring object. The sample measuring cell 1 includes a flexible shell (flexible circulation tube 2), a supporter 10, and an interval adjustment member 12. The supporter 10 includes a first gripping piece 10a having an entrance window 11a of the primary electromagnetic wave 4a, and a second gripping piece 10b having an emission window 11b of the secondary electromagnetic wave 4b, and holds the shell 2 in the radial direction thereof. The interval adjustment member 12 adjusts an interval between both gripping pieces 10a, 10b. The shell 2 is deformed to adjust the optical path length by adjusting the interval between both gripping pieces 10a, 10b by the interval adjustment member 12. |
