Embodiment
Hereinafter, embodiments of the present invention are illustrated.
The glass-cutting of present embodiment is with adhesive sheet (hereinafter sometimes referred to simply as " adhesive sheet ".), possess base material and layer
It is laminated on the adhering agent layer of the one side of base material and is configured.
In the glass-cutting adhesive sheet of present embodiment, the thickness of base material is for 30 μm less than 130 μm.In addition,
Storage modulus of the adhering agent layer at 100 DEG C is 6~50kPa.
In the glass-cutting adhesive sheet of present embodiment, by making base material that there is above-mentioned thickness, glass-cutting can be made
Operability becomes good.In addition, by making storage modulus of the adhering agent layer at 100 DEG C in above range, even if during because of cutting
The frictional heat of generation, when making the temperature of adhering agent layer into the condition of high temperature, can also suppress the vibration of adhesive sheet.Thus glass can be suppressed
Collision or glass plate or chip glass between chip cut the accident collision of face and cutting blade, are collapsed so as to suppress generation
It is broken.As a result, small chip effectively can be obtained from thin glass plate.
1. base material
