1. A combination weighing device comprising:
an electroconductive plate opposed, with an interval, to an electroconductive part that enables detection of water intrusion inside the combination weighing device and constitutes a part of the combination weighing device;
a voltage wire for application of voltage to the electroconductive plate; and
a detector that detects a potential difference between the electroconductive part and the electroconductive plate, wherein
the detector or a controller of the combination weighing device determines presence or absence of water intrusion inside the interval, based on the detected potential difference.
