Abstract
An optical measurement cell including first and second translucent members, which sandwich an internal space storing test liquid, are configured so that light incident on the first translucent member passes through the internal space and is emitted from the second translucent member. The cell includes a first holding member that holds down the circumference of a light transmission area on an outward surface of the first translucent member; a second holding member that holds down the circumference of a light transmission area on an outward surface of the second translucent member; and seal members that are respectively interposed between the first translucent and holding members and between the second translucent and holding members. In addition, areas excluding parts of surfaces of the respective translucent members are coated with coated films, and the end parts of the coated films are positioned on light transmission area sides of the seal members.
