Abstract:
A chip-type light-emitting component (30) includes first terminals (31), and a circuit substrate (20) includes first lands (21), the first terminals (31) and the first lands (21) opposing each other and forming a set positioned at the vertexes of a rectangle. The chip-type light-emitting component (30) further includes signal terminals (32), and the circuit substrate 20 further includes signal lands (22), the signal terminals (32) and the signal lands (22) opposing each other and forming a set positioned inside the rectangle. The amount of solder for a total of areas in which the first terminals (31) and the first lands (21) are soldered together is greater than the amount of solder (52) for a total of areas in which the signal terminals (32) and the signal lands (22) are soldered together.
