In order to measure equivalence ratio (φ_<R_2>) instantaneously, we developed a photoelectric photometer which could measure immediately the luminous intensity of OH, CH, C_2 radical in a flame. By using this apparatus, we investigated the effects of (1) the focusing position of the optical system to the flame front; and (2) the angle between the normal of flame front and the optical axis, with a premixed laminar burner flame. As a result, it was clarified that φ_<R_2> could be measured by the ratio of C_2/CH with 2.2% maximum error. (3) so, we applied this method a Burke-Schumann type diffusion flame, and made it clear that mean <φ_<R_2>>^^- at the flame front was about 1.1 nearly equal to the value assumed until now. (4) and, for the open type diffusion flame, we made it clear that the reason for large <φ_<R_2>>^^- at down-stream was because of insufficient diffusion and the obstruction of burned gas.
