Claim:
1. A probe device which brings a plurality of chips formed by dicing a wafer which is attached to a dicing sheet fixed to a frame, into contact with probes of a tester, the probe device comprising: an actual measurement data acquisition unit configured to acquire actual measurement data showing an actual measurement position of each of the chips on the wafer; a variation amount calculation unit configured to calculate a variation amount, including a direction and an amount of a displacement from an ideal contact position of a probe contact position at which a probe is intended to contact with each of the chips when each of the chips of the wafer is brought into contact with the probe, as a variation amount of each of the chips, based on the actual measurement data acquired by the actual measurement data acquisition unit; and an image generation unit configured to generate a result image for visually showing a calculation result of the variation amount of each of the chips calculated by the variation amount calculation unit in a display of the whole of the wafer.
