We prove the following conjecture recently formulated by Jakobson, Nadirashvili and Polterovich (12): For any Riemannian metric g on the Klein bottle K one has �1(K,g)A(K,g) � 12�E(2 p 2/3), where �1(K,g) and A(K,g) stand for the least positive eigenvalue of the Laplacian and the area of (K,g), respectively, and E is the complete elliptic integral of the second kind. Moreover, the equality is uniquely achieved, up to dilatations, by the metric
