摘要 |
The invention presents a hydrocarbon sensor excellent in yield and high in detection precision. To achieve the object, the invention includes a solid electrolyte layer (1) contained barium-cerium oxide, a pair of electrodes, cathode (2) and anode (3), provided on the solid electrolyte layer (1), a ceramic substrate (4) having a coefficient of thermal expansion nearly same as that of the solid electrolyte layer (1), and a heater (7) provided on the ceramic substrate (4), in which the solid electrolyte layer (1) and ceramic substrate (4) are bonded to each other.
