OPTICAL MEASUREMENT CELL, OPTICA ANALYZER, AND MANUFACTURING METHOD FOR OPTICAL MEASUREMENT CELL

To form on a translucent member a coating that prevents contact with a sample and prevent the coating from peeling off.SOLUTION: Provided is an optical measurement cell 100 comprising a first translucent member 2 and a second translucent member 3 sandwiching an internal space S where a test liquid is accommodated and constituted so that incident light on the first translucent member 2 passes through the internal space S and is emitted from the second translucent member 3. The optical measurement cell 100 further includes: a first presser member 4 for pressing the periphery of a light transmission region A, on an extrorse surface 22 facing the light incident side of the first translucent member 2, which light permeates; a second presser member 5 for pressing the periphery of a light transmission region A, on an extrorse surface 32 facing the light incident side of the second translucent member 3, which light permeates; and seal members 8, 9 interposed between the first translucent member 2 and the first presser member 4 and between the second translucent member 3 and the second presser member 5. A region on the surface of each translucent member 2, 3, except some portion, is coated with a coating X, and an end Z of the coating X is located closer to the translucent region A side than are the seal members 8, 9.SELECTED DRAWING: Figure 2 【課題】透光部材に試料との接触を防ぐ被膜を形成するとともに、その被膜が剥がれてしまうことを防ぐ。【解決手段】被検液が収容される内部空間Ｓを挟む第１透光部材２及び第２透光部材３を備え、第１透光部材２に入射した光が、内部空間Ｓを通過して第２透光部材３から射出するように構成された光学測定セル１００であって、第１透光部材２の光入射側を向く外向き面２２において光が透過する光透過領域Ａの周りを押さえる第１押え部材４と、第２透光部材３の光射出側を向く外向き面３２において光が透過する光透過領域Ａの周りを押さえる第２押え部材５と、第１透光部材２と第１押え部材４との間、及び、第２透光部材３と第２押え部材５との間に介在するシール部材８、９とをさらに備え、各透光部材２、３の表面における一部を除く領域に被膜Ｘがコーティングされており、その被膜Ｘの端部Ｚがシール部材８、９よりも光透過領域Ａ側に位置するようにした。【選択図】図２
