Peeling method

A method for peeling an adherend from a pressure-sensitive adhesive layer by irradiating a laminate in which the pressure-sensitive adhesive layer and the adherend are laminated with light, the method comprising:

• a step of irradiating the pressure-sensitive adhesive layer with the light having a pulse width of 1 second or less and a light irradiation amount of 1,000 mJ/cm2 or more, wherein
• the pressure-sensitive adhesive layer satisfies the following conditions (1) and (2) in terms of a minimum transmittance in a near-infrared region of a wavelength of 800 nm to 2,500 nm and a maximum transmittance in a visible light region of a wavelength of 380 nm to 780 nm, which are measured using a measurement sample in which a first non-alkali glass having a thickness of 0.7 mm is bonded to a first pressure-sensitive adhesive surface of the pressure-sensitive adhesive layer and a second non-alkali glass having a thickness of 0.7 mm is bonded to a second pressure-sensitive adhesive surface of the pressure-sensitive adhesive layer with the pressure-sensitive adhesive layer interposed between the first non-alkali glass and the second non-alkali glass:
• (1) the minimum transmittance is 75% or less, and
• (2) a value obtained by dividing the maximum transmittance by the minimum transmittance is 1.15 or more.
