Abstract
The present invention is to provide: a method for producing a novel hexagonal boron nitride thin film suitable for industrial use such as application to electronics, in which a hexagonal boron nitride thin film having a large area, a uniform thickness of 1 nm or more, with few grain boundaries can be produced inexpensively; and a hexagonal boron nitride thin film. The hexagonal boron nitride thin film according to the present invention is characterized by having a thickness of 1 nm or more, and an average value of the full width at half maximum of the Epeak obtained from Raman spectrum of 9 to 20 cm.
