Abstract: A test carrier includes a base film that holds a die and a cover film that overlaps the base film so as to cover the die. The cover film has a self-adhesive property and is more flexible than the base film. The base film has a through hole. The through hole is formed in the vicinity of a region of the base film which contacts the die.
