Patent ID: 8900701

Claim:
The pressure-sensitive adhesive member, the pressure-sensitive adhesive member comprising a fibrous columnar structure aggregate as a carbon nanotube aggregate, the fibrous columnar structure aggregate comprising a plurality of fibrous columnar structures, wherein: the fibrous columnar structures comprise carbon nanotubes, and the carbon nanotubes comprise carbon nanotubes each having a plurality of walls; a difference between a maximum wall number and a minimum wall number of the wall numbers of the carbon nanotubes is 10 or more, and a relative frequency of a mode of the wall number distribution is 25% or less; and a shear adhesive strength to a glass surface under a 250° C. atmosphere is 0.8 to 1.2 times as high as a shear adhesive strength to the glass surface at room temperature, and wherein the fibrous columnar structure aggregate has a length of 300 μm to 2,000 μm and wherein a shear adhesive strength of the pressure-sensitive adhesive member to glass surface at room temperature is 15 N/cm 2 or more.
