PROBLEM TO BE SOLVED: To provide a reinforcing method of a honeycomb sandwich panel capable of reinforcing a desired region to be reinforced of the honeycomb sandwich panel while suppressing the decrease in the quality of a product or an increase in air force resistance, and a repairing method of the pinhole formed to the outer sheet of the honeycomb sandwich panel. SOLUTION: In the reinforcing method of the honeycomb sandwich panel, the holes 26 communicating with cells 11 are bord in the outer sheet 20 and the peripheral regions of the holes 21 are covered with a cover material 30 to hermetically close the holes 21 while the pressure in the cells 11 is set to high vacuum pressure by drawing a vacuum to provide a resin sump 40 outside the cover material 30 to store a liquid resin 50 and the resin 50 is allowed to flow in the cells 11 through the holes 21 under the high vacuum pressure in the cells 11 to be cured. In the repairing method of the honeycomb sandwich panel, the liquid resin 50 is stored in the resin sump 40 provided outside the pinhole 22, a pressure difference is produced between the inside and outside of the cells 11 adjacent to the pinhole 22 by heating and cooling and the resin 50 in the resin sump 40 is charged in the pinhole 22 through a resin inflow port 41 by the pressure difference to repair the honeycomb sandwich panel.
