A vortex solid with self-generated randomness is found theoretically in a frustrated Josephson-junction array under external magnetic field with anisotropic couplings. Vortices induced by the external magnetic field develop stripes parallel to the direction of weaker coupling. It is shown analytically that there is a continuous, gapless band of metastable states in which stripes are deformed randomly by transverse undulation. The vortex solid with the frozen undulation in a metastable state freely slides along the direction of stronger coupling, thereby destroying the ordering of phases even at zero temperature, but is jammed along the direction of weaker coupling.
