Abstract
A radiation detection apparatus comprises a plurality of pixels each including a conversion element which converts incident radiation into a charge, a switching element which transfers the charge, and an interlayer insulation film disposed between the conversion element and the switching element, a gate line to drive the switching element, and a signal line located to intersect with the gate line and configured to read out the charge transferred from the switching element, wherein Ca≧∈0×∈×S/d and 7d≦P/2 is satisfied, where P is a pixel pitch, Ca is a sum total of coupling capacitances between the signal line and the gate line, S is an overlapping area of the signal line and the conversion element, d is a thickness of the interlayer insulation film, ∈ is a relative dielectric constant of the interlayer insulation film, and ∈0 is a vacuum dielectric constant.
