An imaging panel (10) is provided that generates an image based on scintillation light obtained from X-ray having passed through an object. The imaging panel (10) includes: a substrate (40); a plurality of conversion elements (15) converting the scintillation light into charges; an insulating film (45, 46) having a plurality of conductive portions (47) that reach the conversion elements (15), respectively; and bias lines (16) formed on the insulating film (45, 46) so as to cover the conductive portions (47), the bias lines (16) being connected to the conversion elements (15) through the conductive portions (47), respectively, and supplying a bias voltage to the conversion elements (15). A dimension of each of the conductive portions (47) in a direction in which the bias lines (16) extend is greater than a dimension of each of the conductive portions (47) in a width direction of the bias lines (16).
