PROBLEM TO BE SOLVED: To provide a fiber base material which can reduce stress acting on an end part of a base part positioned in a direction separating from a rising part, and provide a fiber reinforced composite material and a method of manufacturing the fiber reinforced composite material.SOLUTION: A fiber base material 13 includes two L-shaped laminates 20 which are formed by laminating a plurality of reinforced fiber sheets 12 with reinforced fibers arrayed. The L-shaped laminate 20 includes a base part 21 having a first surface 21c and a second surface 21d, and a bent part 23 bent from the base part 21, and includes a rising part 22 which rises from the base part 21 from the first surface 21c to the second surface 21d. A tapered surface 21b, which is inclined in a separating state from the rising part 22 from a second surface 21d side to a first surface 21c side, is formed on an end part 21a of the base part 21 positioned in a direction separating from the rising part 22. Cut surfaces parallel to the tapered surface 21b are respectively formed on a plurality of one end surfaces of the reinforced fibers positioned on the tapered surface 21b. |
