The invention provides an anti-surge temperature sensor including a detection element, a circuit board, an installation seat, a heat conduction cover, and inserts. The two ends of the installation seat are respectively an installation end and a detection end. The detection element is installed at the detection end of the installation seat. The inserts are installed at the installation end of the installation seat. The heat conduction cover is also arranged on the detection end of the installation seat. The detection element is installed on the installation seat through the circuit board. The inserts are connected with the two poles of the detection element. On the circuit of the inserts and the detection element, a capacitor is connected in parallel to the detection element and connected to the inserts. The capacitor is fixed in the heat conduction cover. Through the shunt capacitor, the influence of current instability on the detection element is avoided. As the sensor adopts patch connection instead of the previous connection mode, the loosening of the connection points is avoided, and the heat conduction adhesive is prevented from deforming under heat during work of the sensor in the process of temperature detection.
