Zusammenfassung:	A shower head that supplies a process gas in a vapor phase growth apparatus includes a mixing chamber; and a plurality of cooling portions provided below the mixing chamber with gaps between cooling portions. The cooling portion includes a cooling hole provided in a horizontal direction, and the gaps extend linearly in the horizontal direction. The shower head further includes, below the gaps, a plurality of buffer regions extending linearly in the horizontal direction. The shower head further includes, below the buffer regions, a shower plate including a plurality of through holes disposed at a predetermined interval. The shower head can uniformly supply the process gas.
