The invention discloses a temperature sensing module and an auxiliary fixed seat body. The temperature sensing module comprises a thermal inductance element and an auxiliary fixed seat body, wherein the thermal inductance element comprises a sensing head and a plurality of conductive pins, and a plurality of joints are formed by correspondingly connecting the plurality of conductive pins and a plurality of lead wires; the auxiliary fixed seat body comprises a fixed part, an extension part, an accommodating part and a cover body; a plurality of grooves are formed on the extension part to accommodate part of the plurality of conductive pins, part of the plurality of lead wires and the plurality of joints; the accommodating part is arranged between the fixed part and the extension part to accommodate the sensing head; and a plurality of ribs corresponding to the grooves are formed on the cover body, and a plurality of buckle parts are arranged on the cover body and buckled with the extension part through the plurality of buckle parts, so that the plurality of ribs are supported against part of the plurality of conductive pins accommodated inside the plurality of grooves, part of the plurality of lead wires and the plurality of joints. The assembling process of the temperature sensing module structure is further simplified, the work time is saved, the manpower cost is reduced, the productivity is improved, and the reliability of electronic devices is improved.
