Abstract: Provided is a digitalization system capable of digitalizing the skills of delicate work. This digitalization system comprises a first sensor mounted on a work tool and which detects a deformation of the work tool when the work tool is pressed against a work target, a second sensor which detects a force applied to the work target or a force applied to the work tool when the work tool is pressed against the work target, and a computer which calculates an angle of a corner formed with the work tool and the work target based on sensor values acquired with the first sensor, and calculates a force applied to the work target when the work tool is pressed against the work target based on sensor values acquired with the second sensor.
