摘要：
A method of taking a crustal core sample, wherein the crustal core sample is obtained in a state coated with an antimicrobial polymeric gel formed of a polymer and an inorganic antimicrobial agent dispersed in the polymer. The inorganic antimicrobial agent is a compound containing at least one of silver, zinc or ions thereof. The inorganic antimicrobial agent is carried on a carrier material. The polymer forming the antimicrobial polymeric gel contains a hydrophilic group, and the antimicrobial polymeric gel contains the inorganic antimicrobial agent in a proportion of 0.0001 to 10.0 mass %.
