Two-dimensional photometry of the nuclear region in the Seyfert galaxy NGC 1275 is reported. Charts of the brightness distribution in the nucleus and the nuclear region confirm the elongation of the nucleus toward the northeast, which may be due to interaction between the nucleus and the starlike detail seven arcsec northeast of it. The nycleus may consist of two or more components. The proportion of the nonstellar component in the radiation from the nucleus was 90 and 75 percent, respectively, for the 5 and 10 arcsec diaphragms in the 4800-6650 A spectral region.
