A technique and the like for monitoring changes in blood pressure with a simpler configuration. A blood pressure change detection device that detects a blood pressure change of a subject, based on a pulse wave detection unit that detects a pulse wave of the subject, and a change in a pulse wave signal detected by the pulse wave detection unit, A blood pressure change detection device including a blood pressure change detection unit that detects a change in blood pressure. [Selection] Figure 1【課題】より簡単な構成により、血圧変化を監視する技術等を提供する。【解決手段】被験者の血圧変化を検出する血圧変化検出装置であって、被験者の脈波を検出する脈波検出部と、前記脈波検出部により検出された脈波信号の変化に基づいて、血圧の変化を検出する血圧変化検出部とを有する血圧変化検出装置。【選択図】図１
