The recent experimental data of both ππ/Kπ scattering and production processes, suggesting the existence of scalar σ and κ mesons, are reviewed. In many ππ/Kπ production processes the direct effects of their productions are observed, while they are, because of chiral symmetry, hidden in scattering processes, and now σ(500〜600) and κ(800〜900) are considered to be confirmed experimentally. The recent criticism on our method of analyses, which is based on the long believed prejudice of universal ππ/Kπ phase through scattering and production amplitudes, is explained not to be valid.
