PROBLEM TO BE SOLVED: To prevent electrodes of an electrostatic capacity type liquid concentration sensor for measuring a liquid concentration of a liquid mixture of which the dielectric constant varies in response to a mixing ratio from contacting directly with the liquid mixture. SOLUTION: The present invention relates to electrode structure of the electrostatic capacity type liquid concentration sensor for detecting the dielectric constant varied in response to the concentration of the liquid mixture to measure the liquid concentration. The three electrodes 31, 32, 33 for detecting the liquid concentration are connected, while coated with a film 21, to be formed integrally. COPYRIGHT: (C)2005,JPO&NCIPI
