<p>The invention relates to a gas burner comprising a metal burner membrane having a base section (201), a dosing section (203) and a transition region in between (202). The shape of the membrane is such that the smallest radius of curvature of the transition zone is smaller than the smallest radius of curvature of the base section. Furthermore the burner membrane uninterruptedly flows over from the base section through the transition region into the closing section. The advantages of such a gas bunner am amongst others a large dynamic power range, an improvadflame front and a low production cost.</p>
