PURPOSE:To sense the pressure drop of a liquid to be detected and to increase electrical connections by providing a flow rate restricting tube to the contact part between a working electrode and current collector. CONSTITUTION:A cylindrical electrolytic diaphragm 1 and current collector 2 are provided into a housing 4 formed with a flow passage 3 in which the working electrode 11 is packed. A cylindrical counter electrode 6 is provided to the outside of the diaphragm 1 and a reference electrode 5 is disposed so as to be in proximity to a liquid junction part 5a. A counter electrode liquid 7 is filled into a container 10 in which the diaphragm 1, the current collector 2 and the counter electrode 6 are housed to immerse the same in the liquid 7. The flow rate restricting tube 12 is provided to the contact part between the working electrode 11 and the current collector 2. the electrical connection of the current collector 2 and the working electrode 11 is made sure and the pressure drop in the contact part is decreased by providing the flow rate restricting tube 12. The liquid to be detected is admitted into the detector through an inlet 14 and is passed through the flow passage 3 then through the working electrode 11 in the electrolytic diaphragm 1; thereafter, the liquid is passed through the flow passage 15 of the flow rate restricting tube 12 and is discharged from an outlet 16.
