Abstract: We prove the Kirillov-Reshetikhin conjecture concerning certain finite dimensional representations of a quantum affine algebra ${\mathbf U}_q(\widehat{\mathfrak g})$ when $\widehat{\mathfrak g}$ is an untwisted affine Lie algebra of type $ADE$. We use $t$-analog of $q$-characters introduced by the author in an essential way.
