Gas sensor element, gas sensor and control system of gas sensor

A gas sensor element having at least one cell that includes a solid electrolyte substrate and a pair of electrodes having the solid electrolyte substrate intimately put therebetween, so that the gas sensor element outputs an information signal representative of a concentration of a specified gas in a gaseous environment,

• in which:
• the cell is of a type in which, for outputting the information signal, current is forced to flow through one of the paired electrodes, the solid electrolyte substrate and the other of the paired electrodes;
• a compensating resistor is integrally provided by the gas sensor element, the compensating resistor having a resistance value reflected by a correction information used for correcting the information signal;
• and
• the compensating resistor is connected in parallel with the cell through a pair of current flow lines and placed at a position electrically isolated from the solid electrolyte substrate.
