Claim 7:
8. The terahertz wave control element according to claim 5, wherein the photoreactive polymer comprises any one photoreactive side chain selected from the group consisting of the following formulae (11) to (13):, wherein A independently represents a single bond, —O—, —CH2—, —COO—, —OCO—, —CONH—, —NH—CO—, —CH═CH—CO—O—, or —O—CO—CH═CH—;
X represents a single bond, —OCO—, —OCO—, —N═N—, —CH═CH—, —C≡C—, —CH═CH—CO—O—, or —O—CO—CH═CH—, and in a case where the number of X is 2, these Xs may be the same or different;
l represents an integer of 1 to 12, m represents an integer of 0 to 2, and m1 represents an integer of 1 to 3; and
R represents a ring selected from a monovalent benzene ring, a monovalent naphthalene ring, a monovalent biphenyl ring, a monovalent furan ring, a monovalent pyrrole ring and a monovalent alicyclic hydrocarbon having 5 to 8 carbon atoms, or a group in which the same or different two to six rings selected therefrom are bonded through a bonding group B, wherein a hydrogen atom bonded thereto may be each independently replaced with —COOR0 (wherein R0 represents a hydrogen atom or an alkyl group having 1 to 5 carbon atoms), —NO2, —CN, —CH═C(CN)2, —CH═CH—CN, a halogen group, an alkyl group having 1 to 5 carbon atoms, or an alkyloxy group having 1 to 5 carbon atoms, a hydroxy group, or an alkoxy group having 1 to 6 carbon atoms.
