We report the results obtained by a systematic, broadband (0.5--150 keV)X-ray spectral analysis of moderately obscured (Compton-thin; $22 \leq \logN_{\rm H} < 24$) active galactic nuclei (AGNs) observed with Suzaku andSwift/Burst Alert Telescope (BAT). Our sample consists of 45 local AGNs at$z<0.1$ with $\log L_{\rm 14-195\1mmkeV} > 42$ detected in the Swift/BAT70-month survey, whose Suzaku archival data are available as of 2015 December.All spectra are uniformly fit with a baseline model composed of an absorbedcutoff power-law component, reflected emission accompanied by a narrowfluorescent iron-K$\alpha$ line from cold matter (torus), and scatteredemission. Main results based on the above analysis are as follows. (1) Thephoton index is correlated with Eddington ratio, but not with luminosity orblack hole mass. (2) The ratio of the iron-K$\alpha$ line to X-ray luminosity,a torus covering fraction indicator, shows significant anti-correlation withluminosity. (3) The averaged reflection strength derived from stacked spectraabove 14 keV is larger in less luminous ($\log L_{\rm 10-50\1mmkeV} \leq 43.3$;$R= 1.04^{+0.17}_{-0.19}$) or highly obscured AGNs ($\log N_{\rm H} > 23$; $R =1.03^{+0.15}_{-0.17}$) than in more luminous ($\log L_{\rm 10-50\1mmkeV} >43.3$; $R= 0.46^{+0.08}_{-0.09}$) or lightly obscured objects ($\log N_{\rm H}\leq 23$; $R = 0.59^{+0.09}_{-0.10}$), respectively. (4) The [O IV] 25.89$\mu$m line to X-ray luminosity ratio is significantly smaller in AGNs withlower soft X-ray scattering fractions, suggesting that the [O IV] 25.89 $\mu$mluminosity underestimates the intrinsic power of an AGN buried in a smallopening-angle torus.
