The invention provides an embedded type force measuring device of a strain sensitive element. The embedded type force measuring device comprises a top plate, stand columns, a bottom plate, an external wire fixing body, a stress deformation body and the strain sensitive element, wherein the tops of the four stand columns are connected with four edge corners of the top plate respectively; the bottoms of the four stand columns are connected with four edge corners of the bottom plate respectively; two wiring grooves are formed in the top plate at the tops of the stand columns respectively; thread holes are formed in two ends of the wiring grooves in an array manner; sensitive element mounting holes are formed in the tops of the stand columns; the external wire fixing body, the stress deformation body and the strain sensitive element form a core measuring part and are mounted in the sensitive element mounting holes. According to the embedded type force measuring device of the strain sensitive element, when the top plate is stressed, the stand columns, the stress deformation body and the strain sensitive element can be synchronously stressed and deformed; the sensitive element is used for sensing a deformation amount and transmitting electricity, corresponding to the deformation amount, to a control unit, so that the stress amplitude of the top plate is calculated; a process is obtained by calibrating in advance.
