Patent ID: 8702934

Claim:
A gas sensor comprising: a gas sensor element that extends in an axial direction and has a detection section that detects a specific gas component in a measured gas at a front-end side thereof, and a plurality of electrode pads at a rear-end side thereof; a plurality of connection terminals that are electrically connected to the plurality of electrode pads, respectively; and an insulated separator that extends along the axial direction and has an inserting hole into which the plurality of connection terminals are inserted, wherein the plurality of connection terminals have a plurality of element side sections that are arranged within the inserting hole and respectively connect to the plurality of electrode pads, and a plurality of external circuit side sections that extend further to the outside in a diametrical direction than an outer surface of the separator through one or more first bending sections from the plurality of element side sections, wherein the gas sensor includes a connector section having an opening that is capable of connecting in the diametrical direction, wherein respective ones of the plurality of external circuit side sections integrally have a first terminal section that extends toward the axial center of the separator through a second bending section that is arranged further to the outside in the diametrical direction than the outer surface of the separator, and a second terminal section that extends to the outside in the diametrical direction through a third bending section from the first terminal section, and wherein the second terminal section is inserted through the opening of the connector section.
