  We investigate the connection between starburst and AGN activity by comparing
the 3.3 {\mu}m PAH eimission with AGN properties. Utilizing the slit-less
spectroscopic capability of the AKARI space telescope, we observe
moderate-luminosity Type I AGN at z~0.4 to measure global starburst activity.
The 3.3 {\mu}m PAH emissions are detected for 7 out of 26 target galaxies. We
find no strong correlation between the 3.3 {\mu}m PAH emission and AGN
luminosity in the limted range of the observed AGN luminosity, suggesting that
global star formation may not be tightly related with AGN activity. Combining
our measurements with the previous 3.3 {\mu}m measurements of the low redshift
Type I AGN in the literature, we investigate the connection between nuclear
starburst and AGN activity. In contrast to global star formation, the 3.3
{\mu}m PAH luminosity measured from the central part of galaxies correlates
with AGN luminosity, implying that starburst and AGN activity are directly
connected at the nuclear region.
