A repair patch for a composite part comprising:

• 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 composite part;
• and
• a removal layer that is provided on the bonding surface peelable from the patch main body,
• wherein 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,
• wherein the processed portion is formed of a plurality of through-holes that penetrate through the removal layer at positions to face end portions of the plurality of fiber reinforced preforms in the thickness direction of the patch main body, the end portions being located in the inclined surface.
