ABSTRACT:
An excellent optical magnetic-field sensor having a magnetooptical element, a polarizer, an analyzer and a substrate is provided which can decrease light loss as well as temperature dependency of the modulation rate and prevent displacement and detachment of the magnetooptical element from the polarizer and the analyzer, wherein a synthetic resin adhesive agent is filled in a space between the magnetooptical element and the polarizer and in a space between the magnetooptical element and the analyzer, and the magnetooptical element, the polarizer and the analyzer are respectively adhered or bonded to the substrate.
