Abstract

A structure material includes a resin, reinforced fibers, and voids. The structure material includes a volume content of the resin being within a range of 2.5% by volume or more and 85% by volume or less, a volume content of the reinforced fibers being within a range of 0.5% by volume or more and 55% by volume or less, the voids being contained in the structure material in a rate within a range of 10% by volume or more and 97% by volume or less, a thickness St of the structure material satisfying a conditional expression: St≥Lf·(1−cos(θf)), and a specific bending modulus of the structure material represented as Ec·ρbeing within a range of 3 or more and 20 or less, and a bending modulus Ec of the structure material being 3 GPa or more.
