    IRAS F10214+4724 is a high-z galaxy (z=2.286) with a enormous far IR
    luminosity, 0.8E14 solar luminosity, which is 10 to 100 times more
    luminous than that of the other IR Luminous galaxies discovered with
    IRAS.The far-IR emission was interpretated by the dust emission heate
    d by an AGN or by the newly star form,so that this object was thought
    to be a prototype galaxy undergoing starburst or a quasar. Recent CO
    observation suggested that the gas consumption time scale is much
    shorter than the dynamical time scale,if the starburst activity would
    be dominate. This results imply the existence of adust-enshrouded
    quasar in this object. We would proposed the survey of the high-absor
    bed hard X-ray emission in this object, which would directly give a
   evidence of a dust-enshrouded
