摘要： A multilayer capacitor includes a multilayer body in which dielectric layers and inner electrodes are alternately laminated, and terminal electrodes formed on the multilayer body. The inner electrodes include first inner electrodes and second inner electrodes alternately arranged. The terminal electrodes include at least three terminal electrodes. The first inner electrodes are electrically connected to each other via a through-hole conductor. The second inner electrodes are electrically connected to each other via a through-hole conductor. At least two first inner electrodes in the first inner electrodes are electrically connected via a lead conductor to at least two respective terminal electrodes whose number is smaller than the total number of the terminal electrodes by at least 1 in the at least three terminal electrodes. At least one second inner electrode in the second inner electrodes is electrically connected via a lead conductor to the remainder of terminal electrodes other than the terminal electrodes electrically connected to the first inner electrodes via the lead conductor. An equivalent series resistance is set to a desirable value by adjusting the number of at least one species of the first and second inner electrodes electrically connected to the terminal electrodes via the lead conductors.
