An optical magnetic-field sensor having a magnetooptical element (6), a polarizer (5), an analyzer (7) and a substrate (8) is provided seeking to decrease loss of the optical amount as well as temperature dependency of the modulation rate and prevent displacement and fall-away of the magnetooptical element from the polarizer and the analyzer. A synthetic resin adhesive agent is filled in a space (9) between the magnetooptical element and the polarizer and in a space (10) between the magnetooptical element and the analyzer, and the magnetooptical element, the polarizer and the analyzer are respectively adhered or bonded to the substrate. <IMAGE> |
