Beschreibung
Zusammenfassung:	Provided are: a pitch-based carbon fiber having a defect number density of 40/m or less, a shape of a cross-section of the pitch-based carbon fiber perpendicular to a longitudinal direction being a circle or an ellipse having oblateness of 0.25 or less, and the pitch-based carbon fiber having a boundary surface in a diametrical direction of the circular cross-section or in a major axis direction of the elliptical cross-section; a method of producing the pitch-based carbon fiber; and a fiber-reinforced plastic.
