Surface treatment agent for surface configured from inorganic material, tool and device having modified surface, and method for manufacturing tool and device

A tool, comprising:

• a modified surface, and
• a polymer comprising a repeating unit (A) and a repeating unit (B) on at least a part of the surface formed of an inorganic material,
• wherein
• the repeating unit (A) comprises a cationic group represented by Formula (1) in a side chain thereof
• where R1 and R2 each independently represents an organic group comprising 1 to 10 carbon atoms, and
• the repeating unit (B) comprises a group represented by Formula (2) in a side chain thereof
• where R3 represents an alkanediyl group comprising 2 to 8 carbon atoms, R4 represents a hydrogen atom or an organic group comprising 1 to 40 carbon atoms, and n has an average value of 1 or more.
