A carbon nanotubes (CNTs)-containing resin composite comprised of a synthetic resin-impregnated aligned CNTs aggregate to have a specific surface area of at least 600 m2/g. Its production method comprises a step of laying down an aligned CNTs aggregate having grown perpendicularly from a substrate, a step of impregnating the laid-down aligned CNTs aggregate with a resin, and a step of shaping the resin-impregnated aligned CNTs aggregate into a sheet. Accordingly, there are provided a CNTs-containing resin composite having a high CNT content and a high degree of alignment and having a desired shape capable of fully taking the advantages of anisotropy intrinsic to CNTs, and a production method capable of producing it with ease.
