While remarkably reducing the botheration and burden on the subject, an apnea/hypopnea condition can be detected correctly and easily, and the type of the condition can be identified. A detecting apparatus for detecting an apnea/hypopnea condition of a living body, includes: an electric current applying electrode section to supply an electric current via electrodes into a cervical region of the living body a measurement electrode section to measure an impedance of the cervical region by the electric current an analysis section which detects an apnea/hypopnea condition based on the measured impedance and an output section which outputs the result of detection.
