The possibility of producing attosecond x-rays through Thomson scattering of laser light off laser-driven relativistic electron beams is investigated. For a <= 200-as, tens-MeV electron bunch produced with laser ponderomotive-force acceleration in a plasma wire, exceeding 10(6) photons/s in the form of similar to 160 as pulses in the range of 3-300 keV are predicted, with a peak brightness of >= 5 x 10(20) photons/(s mm(2) mrad(2) 0.1% bandwidth). Our study suggests that the physical scheme discussed in this work can be used for an ultrafast (attosecond) x-ray source, which is the most beneficial for time-resolved atomic physics, dubbed "attosecond physics.
