In a photoelectric conversion apparatus obtained by arranging and fixing a plurality of semiconductor element substrates onto a base with an adhesive, the levels of the upper surfaces of the substrates are adjusted with a desired thickness of the adhesive so as to set the upper surfaces within the same plane while the distance from the upper surface of the base to the semiconductor element surface of each substrate is kept to a design value, thereby realizing a photoelectric conversion apparatus constituted by a plurality of substrates arranged two-dimensionally, which eliminates level gaps between the substrates, and hence is free from problems such as a decrease in resolution, a deterioration in sensitivity, and peeling of a phosphor and the like.

Sensitivity is freely changeable to another one in correspondence to a photographing mode, and both still image photographing and moving image photographing for example which are largely different from each other in dosage of exposure to radiation and which are also different from each other in required sensitivity are carried out so as to meet that request. A source or drain electrode of a TFT 21 is connected to a signal output circuit 3 through a signal line 14a and an IC 5. A source/drain of a TFT 23 is connected to the signal output circuit 3 through a signal line 14b and the IC 5. Thus, in each pixel 6, any one of the signal lines 14a and 14b is freely selectable when a signal is read out.
