Provided is an affixing device capable of affixing an individual film piece to a workpiece with higher accuracy.　An affixing device (1) comprises: an affixing means (2B) having a first moving means that moves a tool (20) toward a tape member (T), and a second moving means that moves the tool (20) along a direction in which the tape member (T) is fed; a carrier means (3) that moves a table (26) holding a workpiece (W); an image capturing means (4) that captures an image of an individual film piece (t1) positioned at the front; and a control means that is capable of controlling the tool (20) to be pressed against the tape member (T) by sending a command to the first moving means, calculates, on the basis of captured image data from the image capturing means (4), the current position of the individual film piece (t1) positioned at the front, and also calculates a deviation amount between the current position and an affixing reference position, and sends a command to the second moving means and a table moving means to move the tool (20) and the workpiece (W) to locations corresponding to the current position, on the basis of the deviation amount.
