Magnetic excitations in the spin-$\frac{1}{2}$ distorted kagome latticeantiferromagnet Cs$_2$Cu$_3$SnF$_{12}$, which has an ordered ground state owingto the strong Dzyaloshinskii-Moriya interaction, were studied using inelasticneutron scattering. Although the spin-wave dispersion can be qualitativelyunderstood in terms of linear spin-wave theory (LSWT), the excitation energiesare renormalized by a factor of approximately 0.6 from those calculated byLSWT, almost irrespective of the momentum transfer. This inadequacy of LSWT,which is attributed to quantum fluctuations, provides evidence of negativequantum renormalization in the spin-$\frac{1}{2}$ kagome latticeantiferromagnet.
