Zusammenfassung:To increase output of a magnetic sensor.SOLUTION: A magnetic sensor 1 includes a ceramic substrate 2, a GMR layer 5, and an underlying layer 4. The ceramic substrate 2 includes a substrate body 20 and a grace layer 3. The substrate body 20 includes ceramic as a material. The grace layer 3 is formed in a surface of the substrate body 20. The GMR layer 5 has a laminate structure of a plurality of magnetic layers 6 and a plurality of non-magnetic layers 7. The underlying layer 4 is formed between the grace layer 3 and the GMR layer 5. The underlying layer 4 includes a BCC solid solution.SELECTED DRAWING: Figure 1 【課題】本開示は、磁気センサの高出力化を図ることを目的とする。【解決手段】磁気センサ１は、セラミック基板２と、ＧＭＲ層５と、下地層４と、を備える。セラミック基板２は、基板本体２０と、グレーズ層３と、を有する。基板本体２０は、材料としてセラミックを含む。グレーズ層３は、基板本体２０の表面に形成されている。ＧＭＲ層５は、複数の磁性層６と複数の非磁性層７との積層構造を有する。下地層４は、グレーズ層３とＧＭＲ層５との間に形成されている。下地層４は、ＢＣＣ固溶体を含む。【選択図】図１
