The effect of an external electric field on the magnetically induced {sup 6}Li-{sup 40}K Feshbach resonance is investigated theoretically by using the asymptotic bound state model (ABM). An electric field can modify the position and width of the Feshbach resonance to varying extent. However, it hardly changes the background scattering length in the case without open-channel resonance. The width of the s-wave resonance resulting from the p-wave bound state becomes narrow under the action of a strong electric field. The effects of electric field on orbital angular momentum and electronic state of the Feshbach molecule are also discussed.
