Abstract
A thin-film device incorporates a device main body and four terminal electrodes. The device main body has four side surfaces. The terminal electrodes are disposed to touch respective portions of the side surfaces. The device main body includes a lower conductor layer that is not used to form a passive element, and an upper conductor layer used to form the passive element. The upper and lower conductor layers include respective lead electrode portions that have respective end faces located at the side surfaces of the device main body. At the side surfaces of the device main body, the end face of the lead electrode portion of the lower conductor layer and the end face of the lead electrode portion of the upper conductor layer are electrically and physically connected to each other. The terminal electrodes touch these end faces and are thereby connected to the upper and lower conductor layers.
