PROBLEM TO BE SOLVED: To provide a memory card which can easily be taken out of various devices and have a hook part formed for extraction without changing its determined shape. SOLUTION: An MMC mounted with a flash memory comprises a substrate 1 which has respective chips, such as a flash memory and a controller, mounted on its main surface, a housing 2 which contains the chips, etc., so that they are covered, and this housing is provided with a recessed part 21 as a hook part for extraction, specially, on the surface of the substrate 1 on the opposite side from the housing 2, etc., i.e., nearby the front part of the left surface part and right surface part. A dimple in an R shape (with a recessed bottom surface) is so formed as the recessed part 21 almost in the same shape with the housing 2 where the recessed part 21 is not provided on a plane projection. |
