  The CIBER collaboration released their first observational data of the Cosmic
IR background (CIB) radiation, which has significant excesses at around the
wavelength $\sim$ 1 $\mu$m compared to theoretically-inferred values. The
amount of the CIB radiation has a significant influence on the opaqueness of
the Universe for TeV gamma-rays emitted from distant sources such as AGNs. With
the value of CIB radiation reported by the CIBER experiment, through the
reaction of such TeV gamma-rays with the CIB photons, the TeV gamma-rays should
be significantly attenuated during propagation, which would lead to energy
spectra in disagreement with current observations of TeV gamma ray sources. In
this article, we discuss a possible resolution of this tension between the TeV
gamma-ray observations and the CIB data in terms of axion [or Axion-Like
Particles (ALPs)] that may increase the transparency of the Universe by the
anomaly-induced photon-axion mixing. We find a region in the parameter space of
the axion mass, $m_a \sim 7 \times 10^{-10} - 5 \times 10^{-8}$eV, and the
axion-photon coupling constant, $1.2 \times 10^{-11} {\rm GeV}^{-1} \lesssim
g_{a\gamma} \lesssim 8.8 \times 10^{-10} {\rm GeV}^{-1}$ that solves this
problem.
