1. Hexagonal boron nitride fibers comprising hexagonal boron nitride, wherein an X-ray diffraction spectrum of the hexagonal boron nitride fibers includes a diffraction peak having a half-width of 2.0° or less in a region where 2θ is in a range of 20° to 30°:
wherein hexagonal boron nitride fibers comprise an aggregate of particles containing hexagonal boron nitride, and
wherein plate-like particles containing hexagonal boron nitride are aligned irregularly in a direction, forming a fibrous shape with the fiber length in the direction.
