| 摘要 |
A flat detector (1) includes a first flat member (11) and a second flat member (21) both made of a nonmagnetic nonmetal, a first conductive wiring (P1) that generates an alternating magnetic field, the first conductive wiring being disposed on a surface of the first flat member facing toward the second flat member, a first layer (12) made of a nonmagnetic metal and disposed at least on a surface of the first flat member, a second conductive wiring (P2) that detects a signal generated by magnetization reversal of a magnetic material, the magnetization reversal being caused by the alternating magnetic field generated by the first conductive wiring, the second conductive wiring being disposed on a surface of the second flat member facing toward the first flat member, and a second layer (22) made of a nonmagnetic metal and disposed at least on a surface of the second flat member.
