Title:
ELECTROCHEMICAL SENSOR
Document Type and Number:
WIPO Patent Application WO/2023/042537
Kind Code:
A1
Abstract:
The present invention comprises a substrate, an electrode chip having a base material and a thin diamond film, and an insulating resin that seals at least part of the surface of an electroconductive member provided to the electrode chip. The insulating resin is provided such that at least part of the thin diamond film is exposed. An integral value BL per unit area of the ionic strength of organic matter having a molecular weight of 100 or greater is 1.2×106 cts/sec or less when the exposed surface of the thin diamond film is measured through time-of-flight secondary ion mass spectrometry.
