Spontaneous emission spectra from a single quantum dot embedded in a microcavity characterized by the quality factor (Q) are theoretically discussed in the high Q weak coupling region. It is shown that the region should be divided into two subregions in terms of the spectral shape. The spontaneous emission spectrum in one subregion has the Lorentzian line shape, which shows a cavity effect in the line width characterized by Q^<-1> dependence. In the other subregion, the spectral line shape is found to have a "doublet" structure, although it is in the weak coupling region. This doublet is caused by a quantum interference effect.
