A radiation detection apparatus including a sensor unit having photoelectric conversion units two-dimensionally arranged and a scintillator layer which converts radiation into light, comprising a first member disposed on the sensor unit, and a second member disposed on the first member, wherein the scintillator layer is disposed on the second member, and letting n1 be a refractive index of the first member, n2 be a refractive index of the second member, and n3 be a refractive index of the scintillator layer, a relationship of n1<n2<n3 holds.
