Disclosed is a colorless and transparent adhesive composition that can suppress a change in resistance value of a metal wiring. A (meth) acrylic acid ester polymer (A), a 2-phenyl-benzotriazole compound (B), a R 1 R 2 NCH 2 — group at the 1-position, and a benzotriazole having R 3 at an aromatic ring A pressure-sensitive adhesive composition containing the derivative (C). (R 1 and R 2 are each independently a C1-20 alkyl group optionally having a substituent or a heteroatom, a C6-14 aryl group optionally having a substituent or a heteroatom, or H; R 3 is H, a C1-4 alkyl group, a C1-4 alkoxy group or a halogen atom) [Selection] Figure 1 |
