A method of measuring adhesive strength includes setting an evaluation time (t), fixing a substrate and an adhesive member to a measurement device, pulling the adhesive member fixed to the measurement device with a first measurement force (F) for the evaluation time (t), pulling the adhesive member fixed to the measurement device is pulled with a second measurement force (F), which is obtained by increasing the first measurement force (F) by a preset amount, for the evaluation time (t), and determining a reference measurement force (F) which is a static force applied to the adhesive member when a distance by which a first portion of the adhesive member is detached from the substrate is equal to a preset distance (d) is determined.
