MEMORY CARD

PROBLEM TO BE SOLVED: To provide a memory card which can be made small-sized and thin and held strong on the whole. SOLUTION: This memory card has a semiconductor memory which can have its recording contents rewritten and is integrally provided with contact terminals making electric connections with equipment and further equipped with a CSP type semiconductor memory 2 composed of a chip-size package, a mount substrate 1 where the contact terminals 8 are formed by printed wiring, and upper and lower housings 6 and 7 which contain the semiconductor memory and a substrate so as to constitute a memory card main body. The semiconductor memory 2 has its terminals 2a, formed on its reverse surface, on the mount substrate 1 by soldering 2b and fillers 9 and 9b are applied between the package flank of the semiconductor memory 2 and the mount substrate 1 to unite them; while the semiconductor memory 2 is mounted, the mount substrate 1 is held by the upper and lower housings 6 and 7.
