A flash circuit board in a lens-fitted photo film unit includes a board part, and a battery contact part connected to the board part by solder. A part exchanging apparatus for the circuit board includes an eliminating unit, which melts the solder, and removes the battery contact part from the board part while the solder is melted. An assembling unit mounts an unused battery contact part on the board part. The unused battery contact part has an unused form of the first battery contact part. A soldering unit connects the unused battery contact part to the board part by use of solder.
