Claim 10:
11. The terahertz wave control element according to claim 5, wherein the photoreactive polymer comprises a photoreactive side chain represented by the following formula (18) or (19):, wherein A and B each independently represents a single bond, —O—, —CH2—, —COO—, —OCO—, —CONH—, —NH—CO—, —CH═CH—CO—O—, or —O—CO—CH═CH—;
Y1 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;
one of q1 and q2 is 1, and another is 0;
l represents an integer of 1 to 12, and each of m1 and m2 represents an integer of 1 to 3;
R1 represents a hydrogen atom, —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.
