There is provided a novel adhesive composition or underfill composition. An adhesive composition or an underfill composition comprising: a polymer that exclusively includes at least one structural unit of Formula (1) as a repeating unit except a terminal:
{where each of R 1 and R 2 is independently a hydrogen atom or a methyl group; X is a sulfonyl group or a divalent organic group of Formula (2):
(where each of R 3 and R 4 is independently a hydrogen atom or a methyl group; at least one hydrogen atom of the methyl group is optionally substituted by a halogen atom; and m is 0 or 1), and Y is a divalent organic group of Formula (3) or Formula (4):
(where Z is a single bond, a methylene group, a sulfonyl group, an -O- group, or a divalent organic group of Formula (2) where m is 0; R 5 is a hydrogen atom, a methyl group, an ethyl group, or a methoxy group; R 6 is a methyl group, a vinyl group, an allyl group, or a phenyl group; and n is 0 or 1)}; and an organic solvent. |
