A first object of the present invention is to provide a curable composition capable of providing a cured substance in which an inorganic substance exhibits excellent dispersibility and which exhibits high thermal conductivity. A second object of the present invention is to provide a thermally conductive material formed by curing the curable composition and a device with a thermally conductive layer including the thermally conductive material.
The curable composition according to an embodiment of the present invention contains an inorganic substance selected from the group consisting of an inorganic nitride and an inorganic oxide, a compound which has a monovalent substituent selected from the group consisting of a boronic acid group, a boronic acid ester group, an aldehyde group, and a pyridinium group and has a molecular weight equal to or greater than 1,000, and a polymerizable monomer.
