A digital still camera includes a vibration detector for detecting vibrations. The sectional area and electrical resistance of the first wiring film can be enlarged, even in cases where the first wiring film and the second wiring film have almost the same width, because of the larger film thickness of the first wiring film. Termites exposed to concentrations as low as 8 mgkg sand exhibited a significant reduction in tunneling and feeding activity. Redundancy circuitry performs the replacement operation during a memory access operation based upon the information stored in the sets of storage elements.
