  We analyze the ultraviolet (UV) and X-ray data of NGC 1275 obtained with {\it
Swift}/UVOT, XRT, BAT and {\it Fermi} Large Area Telescope over about 10 years
to investigate the origin of the nuclear emission from NGC 1275. We confirm
that the UV and soft/hard X-ray fluxes gradually increased along with the GeV
gamma rays. At times, short-term variations in the UV or soft X-ray spectral
regions showed rapid variations correlated with the GeV gamma-rays. However
there was no significant correlation between the UV and soft X-rays. The UV
spectrum had a narrow spectral shape that could be represented by
single-temperature blackbody radiation. These results could possibly indicate
that the long-term variability of UV and X-ray emissions is caused by the jet,
while the emissions from the accretion disk contribute to the UV and X-ray
bands to some extent.
