摘要

In order to provide an antibacterial and/or sterilizing agent having excellent antibacterial properties and sterilizing properties even at low concentration, the present invention provides an antibacterial agent, sterilizing agent, or antibacterial and sterilizing agent having a repeat unit represented by formula (1) and a repeat unit represented by formula (2), and having as an active component a copolymer having an Mw (Mw denoting weight average molecular weight in terms of polystyrene, measured by gel permeation chromatography, wherein the mobile phase in the gel permeation chromatography is tetrahydrofuran.) of 3,000 or less. [In formula (1), R¹ represents a hydrogen atom or methyl group, Z represents a group forming an organic ammonium salt, -NR⁵R⁶ (R⁵ and R⁶ each independently representing hydrogen atoms, or substituted or unsubstituted hydrocarbon groups.), or substituted or unsubstituted nitrogen-containing heterocyclic groups, and X represents a single-bond or divalent linking group.] [In formula (2), R⁷ represents a hydrogen atom or methyl group, and A represents an aromatic hydrocarbon group, -(C=O)OR⁸, -(C=O)NHR⁹, or -OR¹⁰ (R⁸-R¹⁰ representing a hydrocarbon group or a group having a chain or cyclic ether structure.)]
