Abstract
A semiconductor wafer case provides high resistance to vibration. The semiconductor wafer can be easily accessed from the case. The semiconductor wafer case includes a case body and a holder in which blade-type presser feet are provided. An end of each of the presser feet has a V-shaped cross-section. Spaces are provided between presser feet (32a, 33a) and presser feet (32b, 33b). Two holders of the same shape are provided at opposite sides of the case body so that the holders can hold the semiconductor wafer horizontally.
