PROBLEM TO BE SOLVED: To provide a concentration measuring sensor capable of reducing occurrence of complementary after-image due to sighting of a red color of blood while in use.SOLUTION: A concentration measuring sensor 10 is for measuring a concentration of a substance in blood. The concentration measuring sensor 10 has: an insulative base material 12 whose surface 12a serves as an insulation surface having an insulation property; and a conductive pattern 30 disposed on the surface 12a of the insulative base material 12. A supporting base material 11 supporting the insulative base material 12 is arranged on a back surface 12b of the insulative base material 12. A complementary after-image reducing coloring layer 24 having a color corresponding to a complementary color of the blood is arranged between the insulative base material 12 and the supporting base material 11. |
