A device and a method of transfer printing, wherein a flexible sheet (4) is pressed with fluid pressure to a member (1) to be subjected to transfer printing through another member (3) to be transferred so that the member (3) to be transferred may be spread along the surface of the member (1) to be subjected to transfer printing even if the latter (1) is in the three dimensional shape. Thus, easy and sure transfer printing can be applied to even a three-dimensionally shaped member to be subjected to transfer printing. <IMAGE>
