1. A crimping determination device configured to determine a quality of a crimped state of a wire harness in which a crimping terminal is crimped to an electric wire, the device comprising:
a dropping unit configured to drop a test solution to the wire harness, the wire harness including a crimped portion in which the electric wire is crimped by the crimping terminal, a first electric wire portion in which the electric wire is exposed on a distal end side with respect to the crimped portion, and a second electric wire portion in which the electric wire is exposed on a proximal end side with respect to the crimped portion, the dropping unit being configured to drop the test solution to either one of the first electric wire portion and the second electric wire portion;
an image acquisition unit acquires a first image before the test solution is dropped, and acquires a second image after the test solution is dropped, and
a control unit obtains an outflow rate of the test solution in the other one of the first electric wire portion and the second electric wire portion based on the first image and the second image, and determines the quality of the crimped state of the crimped portion based on the outflow rate.
