Provided are: a wavelength conversion member with which it is possible to improve a light distribution characteristic for the purpose of producing a high quality image; and an image formation device using the same. By using optical elements 106h of a light deflection section 106e to divide a spotlight narrowed to a small diameter by a condenser lens 105, it is possible to condense the light into a relatively thin phosphor layer 106d while reducing each light intensity, and deterioration of the phosphor layer 106d can therefore be suppressed. Furthermore, fluorescence produced from the phosphor layer 106d becomes return light in a scattered state but is refracted by the optical elements 106h of the light deflection section 106e and emitted at an angle close to the incident angle of a light beam incident on the light deflection section 106e. It is therefore possible to restrict expansion of light distribution and emit a parallel light beam by using the low NA condenser lens 105. |
