Beschreibung
Zusammenfassung:	In order to provide a spatial optical phase modulator capable of being made compact and operating at high speed, each of microcells (C) of a spatial optical phase modulator (13) is constituted by an optical phase modulator including a magnetization free layer (C11) and a control part (electrode C12) configured to control a direction of magnetization (arrow M11) of the magnetization free layer (C11). The magnetization free layer (C11) and the control part (electrode C12) are each configured to control the direction of the magnetization (arrow M11) such that the direction of the magnetization (arrow M11) is parallel or substantially parallel to normal directions (arrows kf and kr) of a first optically effective surface and a second optically effective surface (bottom surfaces C111 and C112).
