To solve a problem that a tombstone phenomenon occurs and, in the case of a small one, migration tends to occur on the top surface of an element because the dimension of an external terminal on an end surface of a laminate is different from the dimension of an external terminal on a side surface of the laminate.
In a laminate, which is formed by alternately laminating insulator layers and conductor patterns, a circuit element is formed by the conductor patterns, and the circuit element is connected to between multiple external terminals formed in outside surfaces of the laminate. The multiple external terminals are formed by forming conductors from the bottom surface to side surfaces of the laminate and from the bottom surface to end surfaces of the laminate through a photolithographic technique so that the width of the external terminal formed in each side surface of the laminate is the same as the width of the external terminal formed in each end surface of the laminate and that the length of each external terminal is smaller than the thickness of the laminate.
