We present VR CCD photometry and long-slit spectroscopy of a late type spiral galaxy NGC 7678. The grey scale images and isophotal maps illustrate the presence of a weak bar from which spiral arms emerge. There are many HII regions along the spiral arms, but bright giant HII regions are more concentrated in the massive southern arm. The bright compact nucleus of NGC 7678 is bluer than bulge and bar. The spectral features of the nucleus and HII regoins are very similar but the nuclear spectra shows higher $[NII]{lambda}6583/H_alpha$ than those of the HII regions. The nucleus of NGC 7678 seems to be intermediate type between HII region nulcei and LINERs by the ratio of $[NII]{lambda}6583/H_alpha$, but it is more likely to be HII region-like nucleus if we consider the $[NII]{lambda}6716,6731/H_alpha$ together. The star formation rate is estimated to be about $0.2 M_igodot;yr^{-1}$ based on the $H_alpha$ flux.
