Abstract
An imaging device includes a photoelectric converter and a microlens. The microlens is provided above the photoelectric conversion layer. In a cross-section of the imaging device, an upper surface of the microlens forms a contour line in which a first curve projecting upward is connected to a second curve projecting downward at a first inflection point located between the first curve and the second curve. In this cross-section, a curvature radius of the second curve at a lower end of the second curve is larger than a distance in a thickness direction of the microlens from an upper end of the first curve to the first inflection point.
