1. A lighting apparatus for irradiating a light to an object to be taken by an imaging device, wherein an LED light source device for scattering lights of a plurality types of LEDs of different emission wavelengths by a light guiding member and irradiating them from a light emitting surface in the direction of the lighting optical axis is attached to a casing having an imaging light transmitting section through which an imaging optical axis extends from the imaging device to the object, in which the light guiding member has a plurality of light guiding plates which are stacked with each light emitting surface being directed to the lighting optical axis, each of the light guiding plates is mounted with LEDs at a predetermined pitch on the plane perpendicular to the light emitting surface, and the LEDs are arranged such that the combination of the emission wavelengths is identical for each of the rows in the direction of the lighting optical axis.
