PROBLEM TO BE SOLVED: To provide a taste sensor capable of obtaining stable and accurate measurement data, performing low concentration measurement and having a favorable response speed.SOLUTION: A taste sensor 10 includes a sensor electrode part 12, and a reference electrode part 13. The sensor electrode part 12 comprises an insulation substrate 22 installed on the sensor electrode part. An LB (Langmuir-Blodgett) film 24 is formed on the insulation substrate 22, and a hole 19 in which a taste sample flows is installed on one part of a side wall of the sensor electrode part 12. The area of the hole 19 in which the taste sample flows is retained within a favorable area. A solution entering from the hole comes into direct contact with the LB film 24 and a distance from the hole to the LB film is held constant. The taste sensor 10 can thus obtain highly accurate and stable measurement data at a favorable response speed. |
