Abstract
A composite material 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 is provided with a honeycomb core, a first skin material, a second skin material, a thunder-resistant mesh and a resin material; and the resin material is not arranged in a neighborhood portion which is the region corresponding to the region at the front end of the honeycomb core. A first film adhesive is arranged between the first skin material and the honeycomb core; a second film adhesive is arranged between the second skin material and the honeycomb core; and a fourth film adhesive is arranged in the neighborhood portion of the resin material in a weight per square meter, which is lower than those of the first film adhesive and the second film adhesive.
