The object of the present invention is to provide an individual package of adsorbent for oral administration wherein the adsorbent for oral administration is not squeezed in a heat-sealed region thereof. In addition, the object of the present invention is to provide an individual package of adsorbent for oral administration wherein an adhesion of the adsorbent for oral administration is slight in a vacuumed open region thereof, whereby the adsorbent for oral administration is not flied apart in opening the package.The object of the present invention can be solved by an individual package characterized in that the adsorbent for oral administration is tight-packed using a packaging material having from 4.4×109Ω to 1.0×1016Ω of mean specific surface resistivity in internal surface, under warm condition and/or reduced pressure.本發明之目的在於提供一種在內服用吸附劑的分包包裝體中,在熱封部不會咬入內服用吸附劑之分包包裝體。且,提供一種在真空狀態之開封部附近,內服用吸附劑的附著較少,且在開封時不會使內服用吸附劑飛散之分包包裝體。前述課題可藉由下述特徵之分包包裝體予以解決:將內服用吸附劑在加溫狀態及/或減壓下,以內面表面固有電阻平均值為4.4×109 Ω以上至1.0×1016 Ω以下之範圍的包裝材料予以氣密包裝。1...分包包裝體11...熱封部12...開封上部13...開封下部14...開封用縫線孔眼賦予部
