The phase ([ital cphi]) dependence of the Josephson current [ital I]([ital cphi]) between [ital s] wave and [ital d][sub [ital x]][sup 2][minus][ital y][sup 2] wave superconductors is predicted to be sin(2[ital cphi]), when the junction is formed along the [ital c] axis. This dependence is also obtained when the misorientation angle between the interface and the [ital a]([ital b]) axis of the [ital d][sub [ital x]][sup 2][minus][ital y][sup 2] superconductor is 45[degree] in the [ital a]-[ital b] plane contact junction. In such cases, critical current [ital I][sub [ital c]] is proportional to [ital T][sub [ital c]][minus][ital T] near the transition temperature [ital T][sub [ital c]]. The anomalous magnetic flux dependence of [ital I][sub [ital c]] of the corner junction by Wollman is also predicted.
