Method of adjusting output of gas sensor

A gas sensor output adjusting method comprising:

• preparing a gas sensor element including a lamination of a solid electrolyte body, a target gas-exposed electrode, a reference gas-exposed electrode, and a diffused resistance layer in which a target gas to be measured diffuses, the target gas-exposed electrode being disposed on a first surface of the solid electrolyte body exposed to the target gas, the reference gas-exposed electrode being disposed on a second surface of the solid electrolyte body exposed to a reference gas, the diffused resistance layer being disposed on the first surface of the solid electrolyte body, the target gas-exposed electrode and the reference gas-exposed electrode producing a sensor output;
• and
• decreasing a gas-diffusing sectional area of the diffused resistance layer within which the target gas diffuses as a function of a quantity of the sensor output to be adjusted.

• and
• decreasing a diffusion length of the target gas in the diffused resistance layer as a function of a quantity of the sensor output to be adjusted by removing a portion of the diffused resistance layer obliquely to at least one of the side surfaces of the lamination.
