<P>PROBLEM TO BE SOLVED: To solve such a problem that a space is provided around an electrolyte solution holding body in a conventional constant potential electrolysis gas sensor, and if the constant potential electrolysis gas sensor is arranged in a lateral direction, an electrolyte solution is separated from the electrolyte solution holding body, and respective electrodes cannot be mutually connected through the electrolyte solution, thereby functions as a sensor may be lost. <P>SOLUTION: In a constant potential electrolysis gas sensor, an electrolyte solution chamber for holding an electrolyte solution is formed in a case; a detection electrode, a reference electrode, a counter electrode, and an electrolyte solution holding body are arranged in the electrolyte solution chamber; the detection electrode is arranged on the upper surface side of the electrolyte solution holding body, and the counter electrode is arranged in the opposite lower surface side; and the electrolyte solution holding body is composed of a porous material and has a hollow space part in its inside. <P>COPYRIGHT: (C)2012,JPO&INPIT |
