ABSTRACT:
A radiation detector of this invention has an electrically insulating buffer seat disposed on a front surface of a radiation sensitive semiconductor, in a position outside a radiation detection effective area. A common electrode for bias voltage application is formed to cover the buffer seat. A lead wire for bias voltage supply is connected to a lead wire connection area, located on the buffer seat, of the surface of the common electrode. The buffer seat reduces a shock occurring when the lead wire is connected to the common electrode. As a result, the semiconductor and an intermediate layer are protected from damage which would lead to a lowering of performance. The buffer seat is disposed outside the radiation detection effective area. Thus, the buffer seat is provided without impairing the radiation detecting function.
