The invention provides an LED module which forms a light source apparatus in a simple wiring and an LED light source apparatus. An LED module (30) comprises: an insulating substrate (2) in plate form; first main and sub terminals (3, 5) for connection to an external circuit formed near the first side of the insulating substrate (2); second main and sub terminals (4, 6) for connection to an external circuit formed near the second side opposite to the first side; three or more connecting wires (11-19) formed on the insulating substrate (2) for connecting LEDs (1) continuously aligned at a distance from each other in series; LEDs (1) individually connected between the connecting wires adjacent to each other and connected in series in a same direction; and a first passing wire (8) formed on the insulating substrate (2) for electrically connecting the first sub-terminal (4) to the second sub-terminal (6), wherein a first connecting wire located on one side is electrically connected to the first main terminal, and a second connecting wire (19) located on the other side is electrically connected to the second main terminal (4).
