The utility model discloses a ceramic piezoresistive pressure sensor provided with an adjustable linear line, and belongs to the technical field of electrical apparatus elements. The ceramic piezoresistive pressure sensor comprises a ceramic piezoresistive pressure sensor with an XTR106 as a core element, and is characterized in that a pin (1) and a pin (2) of the core element XTR106 of the ceramic piezoresistive pressure sensor are connected with each other, and then connected to a pin (11) through a nonlinear modified resistor (Rr). Through the line, the linearity of the ceramic piezoresistive pressure sensor is regulated to more than 0.2% from smaller than 0.5%, so that the production performance of the ceramic piezoresistive pressure sensor is better than a diffused silicon pressure sensor, and the cost is lower than that of the diffused silicon pressure sensor.
