Claim:
1. A spatial light modulator comprising: a substrate; a fixed electrode disposed on a surface of the substrate; a connecting section, which has one end of the connecting section connected to the surface of the substrate; a movable section, which is connected to another end of the connecting section, and which swings with respect to the substrate due to elastic deformation of the connecting section; a supporting post section, which extends in a thickness direction of the substrate with one end of the supporting post section connected to the movable section, and which integrally swings with the movable section; a reflecting member, which is connected to another end of the supporting post section, and which has a reflecting surface that integrally swings with the movable section and the supporting post section; a movable electrode, which is disposed on a surface of the reflecting member, the surface of the reflecting member facing the fixed electrode; and a conductive layer, which is disposed on the supporting post section with a film thickness larger than that of the movable electrode, and which electrically connects between the movable section and the movable electrode.
