Abstract
A magnetic sensor includes a diamond substrate and a waveguide body in contact with the diamond substrate. The diamond substrate includes, on a surface not in contact with the waveguide body, a first layer including a diamond crystal on which an NV center is disposed and, on a surface in contact with the waveguide body, a second layer on which a conductive pattern is disposed. The waveguide body includes a line configured to transmit a microwave that generates electron spin resonance to the conductive pattern and an optical waveguide configured to transmit exciting light and fluorescence, the exciting light irradiating the diamond substrate and emitting the fluorescence in the first layer of the diamond substrate.
