GAS SENSOR AND METHOD FOR MANUFACTURING GAS SENSOR

Abstract: a gas sensor includes an electrode portion which includes one or more electrode pairs each having a first electrode and a second electrode opposed to each other in a first direction, with a gap, a sensitive membrane disposed between the first electrode and the second electrode, and a voltage application section which applies a voltage to the electrode portion. when the product of an inter-electrode distance in the first direction between the first electrode and the second electrode and an electrode area of the first electrode in a cut surface orthogonal to the first direction is defined as an inter-electrode volume, a division value obtained by dividing the voltage applied to the electrode portion is greater than 4.2�10v/mand not greater than 2.0�10v/m, and the electrode area is equal to or greater than 2.5�10m.
