The present invention addresses the problem of providing an illumination device which comprises a plurality of light-emitting diodes towards a base comprising a socket, and which can brightly illuminate a broader area. The present invention is an illumination device which comprises a plurality of light-emitting diodes 11 towards a base 2 comprising a socket 6, and which illuminates the surrounding area by means of light from the light-emitting diodes 11, wherein a light-transmitting cylindrical part 12 for light distribution is provided towards the base 2, the light-emitting diodes 11 are provided so as to approach or come into contact with the cylindrical part 12 for light distribution and irradiate light towards the cylindrical part 12 for light distribution, the light-emitting diodes 11 are arranged in a line along the peripheral direction of the cylindrical part 12 for light distribution, and the light from the light-emitting diodes 11 is distributed within the cross section of the cylindrical part 12 for light distribution. |
