    Abstract: Provided is a gas sensor element capable of realizing highly accurate concentration measurement in both environments where the concentration of a specific gas in a measurement target gas is high and where the concentration is low. A gas sensor according to one aspect of the present invention determines whether the concentration of a predetermined gas component in a measurement target gas is higher or lower than a predetermined concentration. If it is determined that the concentration is lower, a specific temperature that a sensor element is to reach as a result of being heated by a heater unit is set to be lower than the specific temperature set if it is determined that the concentration is higher.

    Abstract: The present invention includes recognizing, as positions of outermost circumferential cells, positions each of which is calculated from an average cell pitch of usual cells and each of which is present on an inner side from a circumference of an end face of a honeycomb structure; disposing, on the basis of the recognition, virtual perforation regions at positions on a sheet which correspond to the outermost circumferential cells to be plugged, each of the virtual perforation regions being divided into a plurality of squares; and performing perforation processing of perforating at least one of a plurality of squares in each of the virtual perforation regions. Positions and a number of squares to be perforated in each of the virtual perforation regions are individually set in accordance with each of the positions of the outermost circumferential cells to be plugged to which each of the virtual perforation regions corresponds.
