摘要：
A gas sensor (200) has a gas sensor element (10) including a first measurement chamber (16); a first pumping cell (11) having a first interior pump electrode (11c) and its counterpart electrode (11b); a second measurement chamber (18); a second pumping cell (13) that has a second interior pump electrode (13b); and a beater (50). The heater (50) has a lead section (50a); a first resistance portion (50bx) having a higher resistance than the lead portion (50a); and a main heating portion (50k) having a second resistance portion (50by) having a higher resistance than the first resistance portion (50bx) disposed at a leading end side in a longitudinal direction relative to a leading end of the first resistance portion (50bx). The second interior pump electrode (13b) is located within the first resistance portion (50bx) in the longitudinal direction.
