The anomalies observed in recent cosmic ray experiments seem to strongly
constrain the nature of the dark matter. In this letter, we investigate a
possibility of the fermionic dark matter with a minimal extension of the
standard model. We found that the dark matter decays caused by the dimension
six operators can naturally explain the anomalies.
