A polymer having a structural unit represented by Formula (3): wherein R1 is phenyl in which any hydrogen may be replaced by halogen or alkyl having 1 to 5 carbon atoms; in the alkyl having 1 to 5 carbon atoms, any —CH2—, which is not adjacent to each other, may be replaced by —O—, and any hydrogen may be replaced by halogen; Q1 is hydrogen, halogen, alkyl having 1 to 10 carbon atoms, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cyclohexenyl, or phenyl in which any hydrogen may be replaced by halogen or alkyl having 1 to 5 carbon atoms; in the alkyl having 1 to 10 carbon atoms and alkyl having 1 to 5 carbon atoms which is a substituent of phenyl, any —CH2—, which is not adjacent to each other, may be replaced by —O—, —CH═CH— or —C≡C—, and any hydrogen may be replaced by halogen; and Q3 is a group represented by Formula (4): <—Z0A1-Z1lA2-Z2mA3-Z3nA4p-Z5—  (4) wherein a code <represents a bonding point with silicon; l, m, n and p are independently 0, 1, 2 or 3; and A1, A2, A3, A4, Z0, Z1, Z2, Z3 and Z5 are as defined in claim 1. |
