The CIBER collaboration released their first observational data of the CosmicIR background (CIB) radiation, which has significant excesses at around thewavelength $\sim$ 1 $\mu$m compared to theoretically-inferred values. Theamount of the CIB radiation has a significant influence on the opaqueness ofthe Universe for TeV gamma-rays emitted from distant sources such as AGNs. Withthe value of CIB radiation reported by the CIBER experiment, through thereaction of such TeV gamma-rays with the CIB photons, the TeV gamma-rays shouldbe significantly attenuated during propagation, which would lead to energyspectra in disagreement with current observations of TeV gamma ray sources. Inthis article, we discuss a possible resolution of this tension between the TeVgamma-ray observations and the CIB data in terms of axion [or Axion-LikeParticles (ALPs)] that may increase the transparency of the Universe by theanomaly-induced photon-axion mixing. We find a region in the parameter space ofthe axion mass, $m_a \sim 7 \times 10^{-10} - 5 \times 10^{-8}$eV, and theaxion-photon coupling constant, $1.2 \times 10^{-11} {\rm GeV}^{-1} \lesssimg_{a\gamma} \lesssim 8.8 \times 10^{-10} {\rm GeV}^{-1}$ that solves thisproblem.
