(57) [Problem] To provide an antibacterial agent which does not easily flow out of a water-absorbing polymer due to an external pressure or aging and does not cause a decrease in water-absorbing properties of the water-absorbing polymer, and which is safe for a human body. Further, the present invention provides a water absorbing agent excellent in both water absorbing property and antibacterial property. An antibacterial agent comprising a polymer having a structure represented by the general formula (a), and (In the formula, at least one of R 1 to R 3 is a benzyl group, and the rest is an alkyl group having 1 to 20 carbon atoms. R 4 is a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms. X - is an anionic ion. A is -O- or -N H-. n is 1-10. A) a water-absorbing agent having an antibacterial property in addition to the water-absorbing property, wherein the antibacterial property is derived from a polymer; |
