1. A detector module comprising:
a direct-conversion semiconductor crystal;
a first electrode provided on a first surface side of the semiconductor crystal; and
a plurality of second electrodes provided on a second surface side of the semiconductor crystal opposite to the first electrode with the semiconductor crystal therebetween, wherein
the first electrode includes a first partial electrode and a second partial electrode which are applied with a high voltage independently of each other and divided at least in a channel direction, and
each of the second electrodes faces the first partial electrode or the second partial electrode.
