ABSTRACT:
Provided is an electronic component permitting lead wires or the like to be securely soldered to a plurality of respective terminal electrodes connected to electroconductive members in through holes. On a surface7aof a stack-type piezoelectric device being an electronic component, a lead wire is soldered to a second electrode layer23on one end side in the longitudinal direction of one terminal electrode17out of two adjacent terminal electrodes, and a lead wire is soldered to a second electrode layer23on the other end side in the longitudinal direction of the other terminal electrode17. Since the one end side of one terminal electrode17and the other end side of the other terminal electrode17are located on the side opposite to the side where each terminal electrode is connected to an electroconductive member14in a through hole13, it is feasible to prevent the electroconductive member14in the through hole13from dissolving into a molten solder25. In addition, solders25are prevented from adjoining in the direction perpendicular to the longitudinal direction of the terminal electrodes17, and it is thus feasible to prevent solders25from joining together between adjacent terminal electrodes17, 17.
