<p>Provided is a fluorine-containing resin composition that is for optical element sealing and that can obtain a cured product having superior light resistance and heat resistance. The present invention is a fluorine-containing resin composition that is for optical element sealing and that is characterized by comprising an organic silicon compound (A) and a fluorine-containing polymer (B) having a structural unit represented by formula (L) (in the formula: X1 and X2 are the same or different and are H or F; X3 is H, F, CH3 or CF3; X4 and X5 are the same or different and are H, F, or CF3; Rf is an organic group of which 1-3 hydrogen atoms are substituted with Y (Y being a monovalent organic group containing at least one hydrolysable metal alkoxide site having 1-30 carbon atoms at the terminus, or a monovalent organic group having 2-10 carbon atoms and having an ethylenic carbon-carbon double bond at the terminus) and that is a fluorine-containing hydrocarbon group having 1-40 carbon atoms and optionally having am amide bond or a urea bond, or a fluorine-containing hydrocarbon group having an ether bond, 2-100 carbon atoms, and optionally having an amide bond, a carbonate bond, a urethane bond, or a urea bond; a is an integer from 0 to 3; and b and c are the same or different and are 0 or 1).</p> |
