A sensitivity of a cumulative chemical/physical phenomenon detecting apparatus is improved. Prior to transferring charges at a sensing section to a floating diffusion section, the charges remaining at the sensing section are removed from the sensing section by a potential barrier formed between the sensing section and a charge injection adjusting section.
