The present invention is: a curable polysilsesquioxane compound having a repeating unit represented by the following formula (a-1), wherein said curable polysilsesquioxane compound is characterized by fulfilling a specified requirement relating to 29Si-NMR and having a mass-average molecular weight (Mw) in a specified range; a curable composition containing said curable polysilsesquioxane compound; a cured product made by curing the curable composition; and, a method for using the curable composition as an adhesive for an optical element fixing material or as a sealing material for an optical element fixing material. The curable composition according to the present invention has excellent curing properties and a low refractive index. In formula (a-1), R1 represents a fluoroalkyl group represented by a compositional formula CmH(2m-n+1)Fn. m represents an integer from 1-10, and n represents an integer of at least 2 and no more than (2m+1). D represents a connecting group (except for an alkylene group) which joins the R1 and Si, or represents a single bond. Formula (a-1): R1-D-SiO3/2
