Claim Text:
1. A semiconductor light-emitting device including an optical axis comprising: a circuit board having a top surface, a bottom surface, a first side surface and a second side surface located between the top surface and the bottom surface, and being formed in a substantially rectangular tabular shape, the first side surface and the second side surface located in an opposite direction with respect to each other; a first conductor pattern including a first external electrode, a first wire bonding pad and a die-bonding portion, a second conductor pattern including an second external electrode and a second wire bonding pad, a semiconductor light-emitting chip having a top surface, a bottom surface, a first electrode and a second electrode mounted on the die-bonding pad of the die-bonding portion of the first conductor pattern, the top surface of the semiconductor light-emitting chip having a substantially center formed in either a substantially square shape or a substantially rectangular shape, the center of the top surface of the semiconductor light-emitting chip being located over the central point of the die-bonding pad of the first conductor pattern, the first electrode of the semiconductor light-emitting chip formed either on the top surface of the chip or underneath the bottom surface of the chip, the second electrode of the semiconductor light-emitting chip formed on the top surface of the semiconductor light-emitting chip and being electrically connected to the second wire bonding pad of the second conductor pattern via a bonding wire; a first encapsulating material encapsulating the semiconductor light-emitting chip and a part of the bonding wire in a dome shape on the top surface of the circuit board; a second encapsulating resin covering at least the first encapsulating material and another part of the bonding wire exposed from the first encapsulating material; and wherein each of angles between adjacent lines connecting the central point of the die-bonding pad to the plurality of apical ends of the die-bonding pad forms substantially a same angle.
