摘要：
PROBLEM TO BE SOLVED: To provide a laminated ceramic element capable of precisely detecting temperature, and to provide a mounting structure thereof.
SOLUTION: The mounting structure has an NTC capacitor 1, an NTC thermistor, a choke coil, a switching circuit, a feedback circuit, an amplifier, and a capacitor, all arranged on a substrate S. The NTC capacitor 1 includes: a capacitor element body 15 having a plurality of insulator layers 16 to 18 stacked; first to third internal electrodes 19, 20, and 21 to 24 disposed in the capacitor element body 15; and first to third terminal electrodes 11 to 14 disposed on an external surface of the capacitor element body 15. The first internal electrode 19 is connected to only the first terminal electrode 11; the second internal electrode 20 is connected to only the second terminal electrode 12; the third internal electrodes 21 and 22 are connected to only the third terminal electrode 13; and the third internal electrodes 23 and 24 are connected to only the third terminal electrode 14. The third internal electrodes 21 to 24 are opposed to neither of the first and second internal electrodes 19 and 20 in the stacking direction of the insulator layers 16 to 18.
