摘要

PROBLEM TO BE SOLVED: To provide a polyarylene ether resin excellent in various physical properties such as heat resistance, fire retardancy and dielectric characteristics in a cured product, and to provide a method for producing the same, a curable resin material and a cured product thereof, a semiconductor sealing material, a semiconductor device, a prepreg, a printed circuit board, a build-up film, and a build-up board.SOLUTION: In a polyarylene ether resin, at least one of aromatic nuclei in a polyarylene ether structure (α) has a naphthalene skeleton, and at least one of the aromatic nuclei in the polyarylene ether structure (α) has a structural site represented by formula (1) on the aromatic nucleus, or a structural site further having a side group containing a hydrocarbon group, an alkoxy group, a hydroxyl group and an X atom on the aromatic nucleus containing x and y in formula (1).SELECTED DRAWING: None
