Abstract: A manufacturing method of an electronic device is provided. The manufacturing method of the electronic device includes a detection step. The detection step is used to detect the pressure distribution of a manufacturing element. The detection step includes: providing a detection element; pressing the manufacturing element on the detection element to generate a plurality of indentation patterns; converting the plurality of indentation patterns into a plurality of image data; using the plurality of image data to calculate an image feature value; and comparing a relationship between the image feature value and a threshold, and generating a comparison result.
