A multilayer capacitor according to the present invention comprises a multilayer body 2 including a plurality of dielectric layers laminated together, first internal electrodes 3 and second internal electrodes 4 that are arranged alternately with the dielectric layers interposed therebetween inside the multilayer body 2, first extension portions 5a extended from the first internal electrodes 3 to one lateral side A of the multilayer body 2 at one or a plural number of locations, and second extension portions 5b extended from the first internal electrodes 3 to another lateral side B of the multilayer body 2 at one or a plural number of locations, wherein the length of the first extension portions 5a is different from the length of the second extension portions 5b. As a result, the multilayer capacitor according to the present invention have electrical characteristics combining two electrical characteristics in which series resonance points are formed at different frequencies, the "effective frequency band" with low impedance is widened.
