  The nature of the interaction between active galactic nuclei (AGNs) and their
host galaxies remains an unsolved question. Therefore, conducting an AGN census
is valuable to AGN research. Nevertheless, a significant fraction of AGNs are
obscured by their environment, which blocks UV and optical emissions due to the
dusty torus surrounding the central supermassive black hole (SMBH). To overcome
this challenge, mid-infrared (IR) surveys have emerged as a valuable tool for
identifying obscured AGNs, as the obscured light is re-emitted in this range.
With its high sensitivity, the James Webb Space Telescope (JWST) uncovered more
fainter objects than previous telescopes. By applying the SED fitting, this
work investigates AGN candidates in JWST Cosmic Evolution Early Release Science
(CEERS) fields. We identified 42 candidates, 30 of them are classified as
composites ($0.2\leq f_{\rm AGN, IR}< 0.5$), and 12 of them are AGNs ($f_{\rm
AGN, IR}\geq 0.5$). We report the AGN luminosity contributions and AGN number
fractions as a function of redshift and total infrared luminosity, showing that
previously reported increasing relations are not apparent in our sample due to
the sample size. We also extend the previous results on ultra-luminous infrared
galaxies (ULIRGs, $L_{\rm TIR}\geq 10^{12} L_{\odot}$) to less luminous AGNs,
highlighting the power of JWST.
