Provided is a sputtering target which can give a high water barrier property and a high flexibility to a sputtering film, can keep a high film forming rate certainly in sputtering, and can make damages to an objective substance wherein a film is to be formed as small as possible. In order to realize this, a mixed powder which contains 20 to 80% by weight of a SiO powder, the balance of the powder being made of a TiO 2 powder and/or a Ti powder, is pressed and sintered. The sintered body has a composition of SiαTiβOγ wherein α, β and γ are mole ratios of Si, Ti and O, respectively, and the ratio of α/β ranges from 0.45 to 7.25 and the ratio of γ/(α+β) ranges from 0.80 to 1.70. |
