<P>PROBLEM TO BE SOLVED: To enable easily producing a high performance gas sensor excellent in thermal shock resistance and to enable easily controlling a chamfering process. <P>SOLUTION: A solid electrolyte 11 is placed and fixed on an upper plate 120 of a pressing jig 116. At this time, for example, a main surface (for example, an upper surface) of the solid electrolyte 11 is placed and fixed so as to face a main surface 114a of a guide plate 114, which is, in this case, a through hole 112. Then, the solid electrolyte 11 is inclined in one direction by rotating the upper plate 120 by a movement mechanism and, in this state, moved toward the other main surface 114b of the guide plate 114, thereby protruding a first ridge part (first ridge part 106a) of the solid electrolyte 11 from the through hole 112 of the guide plate 114. Then, the first ridge part 106a is chamfered to form a first chamfered part 104a by sliding a cutter along the other main surface 114b of the guide plate 114. <P>COPYRIGHT: (C)2012,JPO&INPIT |
