摘要： A gas sensor includes: a laminate formed of a plurality of layers including at least one layer of a solid electrolyte; a reference gas chamber formed in the laminate and containing a reference gas; and a reference electrode partially exposed in the reference gas chamber. A portion which is not exposed in the reference gas chamber, of the reference electrode is sandwiched between, among the layers, a first layer and a second layer adjacent to the first layer. When an area of the portion sandwiched between the first layer and the second layer, of the reference electrode is defined as a first area, and an area of a portion exposed in the reference gas chamber, of the reference electrode is defined as a second area, a ratio of the first area to the second area is 0.3 or more.

摘要： A gas sensor includes: a laminate including at least one layer made of a solid electrolyte; a measured gas flow path formed in the laminate; and a pump electrode exposed in the measured gas flow path. In a part of a rear end side region, the pump electrode is sandwiched between a first layer and a second layer or is covered with a covering layer formed on the inner surface of the measured gas flow path. The area of a portion exposed in the measured gas flow path, of the pump electrode is 4 mm2 or more. The area of a portion exposed in the measured gas flow path, of the front end side region is larger than the area of a portion exposed in the measured gas flow path, of the rear end side region.

摘要： A plugged honeycomb structure includes: a plurality of honeycomb segments, a bonding layer, and plugging portions to plug open ends of cells of the honeycomb segment. Each honeycomb segment is configured so that the cells having at least two types of different shapes have a predetermined repeated sequence pattern. A circumferential-wall partially surrounded cell in which a partition wall and a segment circumferential wall are disposed so as to surround the cell has an area of open end that has a specific ratio to an area of open end of a partition-wall entirely surrounded cell including the cross-sectional shape of the circumferential-wall partially surrounded cell. The repeated sequence pattern of the cells is kept at a boundary between two of the honeycomb segments bonded with the bonding layer at an inflow end face and an outflow end face.
