A repair patch is for a composite material to repair a part to be repaired which is a repair target of the composite material. The patch includes a patch main body that is formed by laminating a plurality of fiber reinforced preforms in a thickness direction, and has a bonding surface to be bonded to the part to be repaired; and a removal layer that is provided on the bonding surface to be peelable off from the patch main body. The bonding surface includes an inclined surface that is inclined with respect to the thickness direction of the patch main body. The removal layer includes a processed portion that causes the removal layer to have a shape complementary to a shape of the inclined surface of the patch main body.
