The ultrasmall fixing tape of the present invention includes: an extending portion; and a non-extending portion that is substantially free from extending, in which: the non-extending portion includes securing means in at least part thereof; the ultrasmall fixing tape has a base material layer B; the base material layer B has a thickness of 50 μm or more; and the base material layer B has an upper yield strength in a longitudinal direction thereof at a temperature of 23° C. and a humidity of 50% of from 5 N/25 mm to 15 N/25 mm.

An adhesive composition having excellent adhesiveness to a cycloolefin resin or the like. The adhesive composition of the present invention includes a polymer having a repeating unit derived from a polymerizable compound represented by formula (I): Y—N(Ar)(R) Formula (I), in which Ar represents an unsubstituted or substituted C6 to C14 aryl group or an unsubstituted or substituted C6 to C10 aryl C1 to C3 alkyl group; R represents an unsubstituted or substituted C1 to C6 alkyl group, an unsubstituted or substituted C3 to C6 cycloalkyl group, an unsubstituted or substituted C6 to C14 aryl group, or an unsubstituted or substituted C6 to C10 aryl C1 to C3 alkyl group; and Y represents a polymerizable functional group. In Formula (I), a substituent on Ar and a substituent on R can bond to form a divalent organic group.

Examples described include composite nanofibers sheets that have been “infiltrated” with a polymer (i.e., the polymer has flowed past a surface of the nanofiber sheet and into at least some of spaces within the sheet defined by the nanofibers). An adhesive nanofiber tape is formed when the infiltrating polymer is an adhesive and the adhesive infiltrates the nanofiber sheet from a one major surface of the nanofiber sheet. In other described examples, some portions of nanofibers in the sheet have been conformally coated with at least one metal layer.
