The invention provides a MEMS pressure sensor manufacturing method and an electronic device, and relates to the technical field of semiconductors. The MEMS pressure sensor manufacturing method of the invention comprises a step of forming an etching stop component in a position, corresponding to a to-be-formed pressure trench, on a pressure sensing film and a step of removing the etching stop component. Therefore, the pressure sensing film is prevented from being etched improperly in the process of etching a cover layer to form a pressure trench, the cover layer and the pressure sensing film are prevented from distorting, the reliability and sensitivity of MEMS pressure sensors are improved, and drift of pressure sensors is avoided. The electronic device comprises a MEMS pressure sensor manufactured by the MEMS pressure sensor manufacturing method, and thus has the same advantages.
