A fiber-reinforced resin comprising:
- a fiber bundle comprising a plurality of monofilament layers being laminated, each of the monofilament layers comprising a plurality of monofilaments;
- and
- an adhesive resin adhering the plurality of monofilaments together,
- wherein the monofilaments have a honeycomb-shaped cross section perpendicular to a longitudinal direction of the monofilaments,
- wherein the monofilaments have polygonal or approximately polygonal cross sections perpendicular to the longitudinal direction of the monofilaments,
- wherein the monofilament layers comprises outermost monofilament layers at primary surfaces of the fiber bundle, and an intermediate monofilament layer arranged between the outermost monofilament layers,
- wherein the monofilaments in the outermost monofilament layers have a pentagonal or an approximately pentagonal cross section perpendicular to the longitudinal direction of the monofilaments, and
- wherein the monofilaments in the intermediate monofilament layer have a hexagonal or an approximately hexagonal cross section perpendicular to the longitudinal direction of the monofilaments.
