Abstract
According to an aspect, a fingerprint detection device includes: a substrate; a plurality of drive electrodes provided on one surface side of the substrate and arranged in a first direction; a plurality of detection electrodes provided on the one surface side and arranged in a second direction intersecting the first direction; and an insulating layer provided in a normal direction of the substrate between each of the drive electrodes and the corresponding detection electrodes. The detection electrodes intersect the drive electrodes in the normal direction of the substrate. The detection electrodes include: a first metallic layer; and a second metallic layer positioned closer to the one surface than the first metallic layer to the one surface. The first metallic layer has a reflectance of visible light lower than that of the second metallic layer.
