The new auto power spectra of the cosmic infrared and X-ray background fluctuations reach maximum angular scales of $\\sim$ 3000$''$ and $\\sim$ 5000$''$, respectively. We measure the cross power spectra between each infrared and X-ray band and calculate the mean power above 20$''$. We find that the soft X-ray band is correlated with 3.6 and 4.5$\\mu$m at $\\sim$ 4 $\\sigma$ significance level.
