To provide a fiber-reinforced resin composite having a fiber-reinforced resin layer around a honeycomb core material, wherein the fiber-reinforced resin composite can prevent the rupture of reinforced fibers due to the honeycomb core material and prevent a deterioration in the strength of the fiber-reinforced resin composite.SOLUTION: A fiber-reinforced resin composite includes a honeycomb core material having a plurality of cells that are defined by partition walls and extend in an axial direction, and a fiber-reinforced resin layer that includes continuous fibers wound around the honeycomb core material and is disposed around the honeycomb core material. Between the honeycomb core material and the fiber-reinforced resin layer, provided is a protection layer that prevents the rupture of the continuous fibers.SELECTED DRAWING: Figure 4
