Abstract

See full text

A method of measuring adhesive strength includes 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 is pulled 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) is determined.
