PROBLEM TO BE SOLVED: To provide an electric light bulb type light source apparatus capable of making an EMC (Electro Magnetic Compatibility) countermeasure while restraining the effect of heat from a light source.SOLUTION: An electric light bulb type light source apparatus includes a light source unit, a power source circuit, and a casing. The power source circuit has a primary circuit connected with an external power source, and a secondary circuit combined with the primary circuit in an insulated state and outputting power for driving the light source unit on the basis of the power from the primary circuit. The casing has a translucent cover, and a partial casing section with heat radiation thermally connected with the light source unit and conducted to the secondary circuit, and stores the light source unit and the power source circuit. |
