ABSTRACT:
An oxygen sensor comprises an electrolyte which is shaped into a conical tube having a closed end of small diameter and an open end of large diameter. The wall thickness of the electrolyte is gradually decreased toward the closed end from the open end and that of the closed end is 0.3 to 1.0 mm so as to provide a high sensitivity.
