The purpose of the present invention is to provide a composite material that is capable of suppressing decrease in the strength, which is caused by bending of fibers of a skin material during the time when the composite material is cured. A composite material (1) according to the present invention is provided with a honeycomb core (2), a first skin material (4), a second skin material (6), a thunder-resistant mesh (7) and a resin material (8); and the resin material (8) is not arranged in a neighborhood portion (9) which is the region corresponding to the region at the front end of the honeycomb core (2). A first film adhesive (3) is arranged between the first skin material (4) and the honeycomb core (2); a second film adhesive (5) is arranged between the second skin material (6) and the honeycomb core (2); and a fourth film adhesive is arranged in the neighborhood portion (9) of the resin material (8) in a weight per square meter, which is lower than those of the first film adhesive (3) and the second film adhesive (5).
