We present the star formation rate (SFR) measurements based on the spectral energy distribution (SED) analysis with new submillimeter fluxes combined with archival multiwavelength data for a sample of 52 active galactic nucleus (AGN) host galaxies at z < 0.2. We carried out submillimeter observations using the SCUBA-2 camera at the James Clerk Maxwell Telescope and obtained flux or an upper limit at 450 and 850 μm for each target. By experimenting with the effect of the AGN dust component in the SED fit, we find that the dust luminosity can be overestimated if the AGN contribution is ignored. While the SFR based on the 4000 Å break shows a significant offset compared to the dust-luminosity-based SFR, the SFR obtained by the artificial neural network generally shows consistency, albeit with a large scatter. We find that SFR correlates with the AGN outflow strength manifested by the [O iii] λ5007 emission line, and that AGNs with higher Eddington ratios and stronger outflows are generally hosted by galaxies with a higher SFR, which is consistent with the correlation reported by Woo et al. This suggests no instantaneous quenching of star formation due to AGN feedback.
