Abstract
A displacement sensor includes a first emission particles layer provided to be contactable with a measurement object, and in which first emission particles that emit light at a first wavelength by excitation energy are distributed over at least a one-dimensional extent, a second emission particles layer in which second emission particles that emit light at a second wavelength different from the first wavelength by the excitation energy are distributed over the above one-dimensional extent, and a spacer layer that separates the first emission particles layer and the second emission particles layer in a direction intersecting the above one-dimensional extent, and which includes an excitation energy absorbent that absorbs the excitation energy.
