CUTTING DEVICE AND CUTTING METHOD

A cutting device includes: an imaging module for capturing first marks and third marks, to produce primary image data; and a control module for aligning, by a conveyance mechanism, a cutting jig and an object to be cut that is placed on the cutting jig. The control module compares first positional information including positional information of a specific first mark stored or first positional information with third positional information to calculate a primary displacement amount showing a relative positional displacement between a plurality of cutting grooves and the plurality of third marks, respectively. The conveyance mechanism picks up the object from the cutting jig, and the conveyance mechanism and the cutting jig are moved relative to each other based on the primary displacement amount, to move the object by the primary displacement amount to a primary target position. The cutting mechanism cuts the object along a plurality of cutting lines.
