Derivatives of hydrocarbon groups mean groups having one or more N, O, S, Si, amide, sulfonyl, siloxane, carbonyl, carbonyloxy, etc., at the terminal or molecular chain of a hydrocarbon group. When simply referred to as "organic group," it means a monovalent organic group. Furthermore, "divalent organic group" means a divalent group containing carbon. Such divalent organic groups include divalent groups obtained by removing one more hydrogen atom from an organic group. Similarly, trivalent or higher organic groups mean groups obtained by removing a predetermined number of hydrogen atoms from an organic group.

[0013] The curable composition of this disclosure may have improved applicability by containing fluororesin particles of component (D) in addition to components (A) to (C). Furthermore, the cured product obtained from the curable composition of this disclosure may exhibit excellent dielectric strength.

[0014] This disclosure is not bound by any theory, but the mechanism by which the curable composition of this disclosure exhibits the above effects is presumed to be as follows: The fluoropolyether group-containing silane compound, which is the base material, has low viscosity, and the viscosity increases by adding fluororesin particles, improving the applicability. That is, there is less dripping after application of the curable composition, and gaps between parts and the walls of steps can be uniformly covered. Furthermore, the curable composition has appropriate thixotropy and viscosity, which prevents liquid skipping and clogging during application. In addition, the fluororesin particles have good compatibility with the fluoropolyether group-containing silane compound, which can suppress the incorporation of air bubbles that reduce the dielectric strength into the curable composition, thereby improving the dielectric strength.

[0015] Component (D): Fluorine-containing resin particles

By setting the content of component (D) to 5 parts by mass or more per 100 parts by mass of component (A), the coatability of the curable composition is improved, and the dielectric strength of the resulting cured product is further improved. Alternatively, the content of component (D) may be preferably 120 parts by mass or less, more preferably 100 parts by mass or less, and even more preferably 90 parts by mass or less, for example, 80 parts by mass or less, per 100 parts by mass of component (A).
