Abstract

PURPOSE: To provide a stable general-use composite electrode, by combining a gate-insulating type field-effect transistor electrochemical sensor with a reference electrode composed of an internal electrode and an internal liquid, etc.
CONSTITUTION: A substrate 5, on which a gate-insulating type field-effect transistor 3 capable of responding to ion and a heat-sensing element 4 for temperature compensation capable of responding to temperature are formed, is manufactured by molding of an insulating resin 6, such as silicon resin, etc., excepting a tip ion-responding section and mounted on the tip of an inner cylinder 1. In the inner cylinder 1, several lead wires 7... which are led out from the substrate 5 are arranged as built-in type wires. A gap between tip sections of the inner cylinder 1 and an outer cylinder 2 is blocked by a covering body 11, and a gap between the inner and outer cylinders is filled with an internal electrode 12 which constitutes a reference electrode and is composed of silver and silver chloride and also with an internal liquid 13 consisting of solution of potassium chloride. The covering body 11 is provided with a liquid junction 14 which constitutes a liquid body contacting section between the internal liquid and a specimen liquid.
