The magnetic sensor formed via metal/high-Tc superconductor small contact shows anisotropic properties below the lower-critical-field (Hci). Ag wire was connected directory on the superconductor by ultrasonic bonding method. The resistances was changed by the field parallel to the superconductor surface, while it was not affected by the vertical field. The change is estimated to be 5 {times} 10{sup {minus}5} {Omega}/Gauss. No hysteresis is observed in this paper. Magnetic field direction can be detected by using these properties and deferential measuring method of the resistance.
