The multimode surface acoustic wave filter includes two surface acoustic wave resonators closely arranged on a piezoelectric substrate in a direction perpendicular to the propagation direction of surface acoustic waves and acoustically coupled by a coupling section, each of the surface acoustic wave resonators including an interdigital transducer and two reflectors disposed closely on both sides of the interdigital transducer in a direction parallel to the propagation direction of the surface acoustic waves, the interdigital transducer having an excitation section for exciting the surface acoustic waves and a signal terminal section for inputting an electric signal, each of the reflectors having a grating section and a terminal section, wherein the velocity of surface acoustic waves propagating through the coupling section is a little larger than the velocity of the surface acoustic waves propagating through the excitation section of the interdigital transducer.
