1. A method of measuring adhesive strength, the method comprising:
setting an evaluation time (te);
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 (Fe1) for the evaluation time (te);
pulling the adhesive member fixed to the measurement device with a second measurement force (Fe2), which is obtained by increasing the first measurement force (Fe1) by a preset amount, for the evaluation time (te); and
determining a reference measurement force (Fes) 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 (dt).
