PROBLEM TO BE SOLVED: To provide a copolymer of high fluorescence intensity in view of the fact that when a copolymer is to be used as a macromolecular fluorophor, although its high fluorescence intensity is demanded, those of conventional copolymers are insufficient yet. SOLUTION: The copolymer of high fluorescence intensity is composed of two or more kinds of recurring units. This copolymer meets the relationship(A):(Qii×100)/(Qii+Qij)≥(c<SB>i</SB>×100)/[3(c<SB>i</SB>-c<SB>j</SB>)] for all of the combinations of A<SB>i</SB>and A<SB>j</SB>meeting c<SB>i</SB>≤c<SB>j</SB>[ wherein, A<SB>i</SB>and A<SB>j</SB>(i≠j) are two kinds of recurring units arbitrally selected from those included in the copolymer; c<SB>i</SB>and c<SB>j</SB>are the contents( mol% ) of A<SB>i</SB>and A<SB>j</SB>in a total of the recurring units in the copolymer, respectively; among diads regarding A<SB>i</SB>, Qii is the amount of (A<SB>i</SB>-A<SB>i</SB>) and Qij is the amount of (A<SB>i</SB>-A<SB>j</SB>) ]. This copolymer emits fluorescence in a solid state and has a number-average molecular weight of 10<SP>3</SP>to 10<SP>8</SP>calculated as polystyrene. COPYRIGHT: (C)2005,JPO&NCIPI
