Abstract

An optical unit is provided with an integral light condensing section and a light transmitting section. The light condensing section is in a shape of a parabolic body of rotation substantially widening from a proximal end toward a distal end with a concave section opening at a proximal end face to accommodate a light emitting element, a side circumferential face to reflect the light from the light emitting element inward and a distal end face to introduce the light from the light emitting element into the light transmitting section. The light transmitting section is a substantially cylindrical shape of a smaller diameter than the light condensing section, and comprises a proximal end face to introduce the light from the light condensing section, a side circumferential face to reflect the light introduced from the proximal end face inward and a distal end face to emit the light.
