A light control device with a reduced electric loss is provided which can suppress a phenomenon of electrically reflecting a high-frequency signal even when it employs a dielectric anisotropic substrate. A light control device includes a signal electrode formed on a dielectric anisotropic substrate and ground electrodes disposed with the signal electrode interposed therebetween. Here, the signal electrode includes at least two signal electrode portions disposed in directions in which the dielectric constant of the substrate is different from each other and a curved connecting portion connecting the at least two signal electrode portions. The connecting portion is configured so that the characteristic impedance in parts connected to the at least two signal electrode portions is equal to that of the corresponding signal electrode portion, and the characteristic impedance in the connecting portion between the at least two signal electrode portions continuously varies.
