A composite material structure (1) is provided with: a metal member (2) that is planarly formed of a metal such that a thermal expansion coefficient in the first direction (X) along a main surface is larger than a thermal expansion coefficient in the second direction (Y), which is along the main surface, and is orthogonal to the first direction (X); and a resin member (4), which is formed of a fiber-reinforced resin, bonded to the main surface of the metal member (2), and is formed such that a fiber quantity in the second direction (Y) is larger than a fiber quantity in the first direction (X). |
