    • In a radiation detector in which scintillator layers are directly formed on all the light receiving parts of a plurality of photoelectric conversion substrates, space and level difference between the adjacent photoelectric conversion substrates are determined so that the effects of these space and level difference fall within a range corresponding to the effect of one photoelectric conversion element. Specifically, the space between the adjacent photoelectric conversion substrates is equal to or less than 133 μm and the level difference between the adjacent photoelectric conversion substrates is equal to or less than 100 μm. Accordingly, the scintillator layers can be directly formed on all the light receiving parts of the plurality of photoelectric conversion substrates. This prevents degradation in MTF and sensitivity and reduces manufacturing costs.
    • 在其中闪烁体层直接形成在多个光电转换基板的所有光接收部分上的辐射检测器中,确定相邻光电转换基板之间的空间和电平差,使得这些空间和电平差的影响落在 范围对应于一个光电转换元件的影响。 具体地说,相邻的光电转换基板之间的间隔等于或小于133μm,并且相邻的光电转换基板之间的电平差等于或小于100μm。 因此,闪烁体层可以直接形成在多个光电转换基板的所有光接收部分上。 这可以防止MTF和灵敏度下降,并降低制造成本。
