摘要

An electronic component thickness measurement method includes extracting, from a plurality of second reference lines in first image data and a plurality of second reference lines in second image data, only a second reference line at which a difference in intensity peak between respective second reference lines at a same position in the first image data and the second image data is smallest, and forming third image data including a first reference line and the extracted second reference line, and calculating a thickness of the electronic component from a distance between the first reference line and the second reference line in the third image data.
