Abstract
A light detection element includes: a magnetic element 10 as a light detection portion for detecting light; a first electrode 11 having optical transparency; and a second electrode 12. The magnetic element 10 is, for example, a magnetoresistance effect element such as an MTJ pillar. The magnetic element 10 is located between the first electrode 11 and the second electrode 12. The light detection portion has a rectangular shape with different lengths of long side and short side when viewed in a plan view from a first direction, which is a direction of incidence of the light. The light detection element can provide polarization selectivity and/or wavelength selectivity.
