Abstract
Provided is a pressure measurement method including moving a detection unit that detects a force accompanying deformation of a flexible tube by a predetermined distance in a load measurement direction of the flexible tube, measuring a reaction force of the flexible tube by the detection unit, and measuring an internal pressure of the flexible tube on the basis of the reaction force.
