PROBLEM TO BE SOLVED: To provide a stimulation-responsive material excellent in film formability and transparency. SOLUTION: An alicyclic vinyl ether copolymer comprises at least one alicyclic vinyl ether represented by formula (1) and at least one 10-30C long-chain alkyl group-containing vinyl ether in the main chain. In the formula, R<SP>1</SP>to R<SP>12</SP>each independently represent a hydrogen atom, a deuterium atom, or a 1-15C hydrocarbon group; A<SP>1</SP>to A<SP>4</SP>each independently represent a hydrogen atom, a deuterium atom, or a 1-15C hydrocarbon group; R<SP>1</SP>to R<SP>12</SP>and A<SP>1</SP>to A<SP>4</SP>may together form an aliphatic ring; n represents an integer of 0-3; and m represents an integer of 0-2.
