Abstract
A laser illumination device includes a light source component, a micro-element lens, and a meniscus lens. The light source component emits a laser beam. The micro-element lens spreads out the laser beam. The meniscus lens has an incident face on which the laser beam from the micro-element lens is incident, and a light emission face that is provided on the opposite side from the incident surface and includes a convex shape, and the meniscus lens has a negative power for spreading out the incident laser beam from the micro-element lens.
