We perform a systematic, multiwavelength spectral energy distribution (SED)analysis of X-ray detected Active Galactic Nuclei (AGNs) at $z=0.2-0.8$ withSDSS counterparts in the Stripe 82 region, consisting of 60 type-1 and 137type-2 AGNs covering a 2--10 keV luminosity range of $41.6 < {\rm log}\ L_{\rmx} < 44.7$. The latest CIGALE code, where dusty polar components are included,is employed. To obtain reliable host and AGN parameters in type-1 AGNs, weutilize the image decomposed optical SED of host galaxies by Li et al. (2021)based on the Subaru Hyper Suprime-Cam (HSC) images. The mean ratio of blackhole masses ($M_{\rm BH}$) and stellar masses ($M_{\rm stellar}$) of our X-raydetected type-1 AGN sample, $\log (M_{\rm BH}/M_{\rm stellar}) = -2.7\pm0.5$,is close to the local relation between black hole and stellar masses, asreported by Li et al. (2021) for SDSS quasars. This ratio is slightly lowerthan that found for more luminous ($\log L_{\rm bol} > 45$) type-1 AGNs at$z\sim1.5$. This can be explained by the AGN-luminosity dependence of $\log(M_{\rm BH}/M_{\rm stellar})$, which little evolves with redshift. We confirmthe trend that the UV-to-X-ray slope ($\alpha_{\rm OX}$) or X-ray-to-bolometriccorrection factor ($\kappa_{2-10}$) increases with AGN luminosity or Eddingtonratio. We find that type-1 and type-2 AGNs with the same luminosity rangesshare similar host stellar-mass distributions, whereas type-2s tend to showsmaller AGN luminosities than type-1s. This supports the luminosity (orEddington ratio) dependent unified scheme.
