Abstract

To provide a photoelectric conversion element capable of functioning as a photoelectric conversion element when a compound having a specific structure is applied to the photoelectric conversion element, causing the element to exhibit a low dark current, and reducing the range of increase in the dark current even when the element is heat-treated, and an imaging device equipped with such a photoelectric conversion element. A photoelectric conversion element having a photoelectric conversion film which is sandwiched between a transparent electrically conductive film and an electrically conductive film and contains a photoelectric conversion layer and an electron blocking layer, wherein the electron blocking layer contains a compound having, as a substituent, a substituted amino group containing three or more ring structures.
