Composite material sheet for analysis of substances originating from living body or analogues thereof

摘要

A composite material sheet favorably utilizable for analysis of substances originating from living body or its analogues has partitions two-dimensionally extending on a sheet plane to form on the sheet plane plural fine sections surrounded by the partitions and porous material portions each of which is placed in the fine section, in which the partitions are made of material having a mean density of 0.6 g/cm<3 >or higher and the porous material portions have a mean density of 1.0 g/cm<3 >or lower, under the condition that the mean density of material of the partitions is higher than the mean density of the material of the porous material portions.
