Abstract: A base material processing apparatus includes a first edge sensor, a second edge sensor, and a displacement amount calculation part. The first edge sensor acquires a first detection result (R1) by detecting the position of an edge of a base material in the width direction at a first detection position. The second edge sensor acquires a second detection result (R2) by detecting the position of the edge of the base material in the width direction at a second detection position. The displacement amount calculation part calculates the amount of displacement in the position of the base material in the transport direction on the basis of the first detection result (R1) and the second detection result (R2). Accordingly, the amount of displacement in the position of the base material in the transport direction can be detected without depending on images such as register marks.
