An experiment to measure the Σ+p scattering cross sections was carried out at KEK 12 GeV proton synchrotron. A scintillating fiber active target system was used as a hydrogen target for the hyperon production and subsequent hyperon-nucleon scattering. Out of 1.3 × 10 6 hyperon production events, 31 events were identified as Σ+p elastic scattering events in the momentum region of 350 ≤ p Σ+ ≤ 750 MeV/c. Differential cross sections in the angular region of -0.8 < cosθCM < 0.8 and integrated cross sections with respect to the incident momentum were obtained. They were compared with the theoretical calculations.
