A composite material structure having holes and enabling weight reduction is provided. The composite material structure is provided with: a forward section (3a) that is a composite material made of fiber reinforced plastic, and extends in one direction; an aft section (3c) that is a composite material made of fiber reinforced plastic, and extends in the one direction as separated by a predetermined distance from the forward section (3a); and an access panel (5) that is provided between the forward section (3a) and the aft section (3c), and has a shorter dimension in the one direction than the forward section (3a) and the aft section (3c). The access panel (5) is removable, and disposed as fixed in an orthogonal direction that is substantially orthogonal to the one direction and shiftable in the one direction with respect to the forward section (3a) and the aft section (3c).
