Abstract
【解決手段】 窒化珪素から成る多孔質基材の外周面に、ポリシラザンを含む溶液が塗布され、次いで、焼成処理が施されることによって細孔径が0.62(nm)程度、厚さ寸法が100〜200(nm)の範囲内で、Si−C、Si−N、並びにSi−O−N、Si−O−Cのような結合を備えたアモルファス状態の多孔質セラミックスから成る多孔質の膜16が生成される。このとき、ポリシラザンを含む溶液として数平均分子量が2000〜5000(g/mol)の範囲内、粘度が20〜200(mPa・s)の範囲内のものが用いられていることから、その溶液を中間層14の表面に適度な厚みで塗布することが可能になり、焼成処理によって生成される多孔質セラミック膜が100〜200(nm)程度の薄い厚さ寸法と、0.5〜1.0(nm)程度の小さい細孔径とを備えるものとなる。
