The invention discloses an unmanned aerial vehicle inertia measuring module which comprises a shell body component (1). A first circuit board (2), a second circuit board (3), a buffering device (4) and a thermolator (5) are contained in a hollow shell body component cavity. The first circuit board is fixed on the inner wall of the shell body component. The second circuit board is fixed in a first groove in the bottom of the thermolator. An inertia sensor is arranged on the second circuit board. The second circuit board is connected with the first circuit board through a connecting wire (8). The buffering device comprises an upper damping cushion (41) and a lower damping cushion (42). The upper damping cushion and the lower damping cushion are fixedly attached to the upper surface and the lower surface of the thermolator respectively. The inertia measuring module is provided with the thermolator, so that the inertia measuring module is kept at the best working temperature, and accordingly measured data accuracy and precision are guaranteed. The inertia measuring module is simple and compact in structure, and high stability and safety are achieved.
