Light emission body and illumination device

A light emission body comprising:

• a fluorescent substance layer that has a light irradiation surface which is irradiated with excitation light and a light emitting surface which is located on a side opposite to the light irradiation surface, and that emits the excitation light and fluorescence which is obtained by wavelength-converting a part of the excitation light, from the light emitting surface;
• a light blocking layer that blocks the excitation light and the fluorescence which are emitted from the light emitting surface;
• and
• a scattering layer that is provided on the light emitting surface side and scatters the excitation light and the fluorescence which are not blocked by the light blocking layer;
• wherein the fluorescent substance layer is configured by a small void fluorescent substance plate that generates the fluorescence as the excitation light is applied, and
• wherein the excitation light is laser light in a wavelength range larger than or equal to 420 nm and smaller than or equal to 490 nm.
