Method for producing thin glass resin laminate piece
Provided is a method of producing a thin glass resin laminate piece, which includes cutting a thin glass resin laminate through laser processing, and by which a thin glass resin laminate piece capable of preventing the occurrence of air bubbles when bonded to an adherend can be obtained. The method of producing a thin glass resin laminate piece of the present invention includes a step of subjecting a thin glass resin laminate including a thin glass, a resin layer, and a pressure-sensitive adhesive layer in the stated order to laser processing to cut the laminate, wherein a thickness (μm) of the pressure-sensitive adhesive layer and a creep characteristic (μm/Hr) of the pressure-sensitive adhesive layer have a relationship of (thickness (μm)) 2 ×creep characteristic (μm/Hr)≥50×10 3 (μm 2 ·μm/Hr).
