A slit lamp microscope for measuring a corneal curvature radius is provided to reduce manufacturing cost and readily manufacturing the corneal curvature radius. A slit lamp microscope for measuring a corneal curvature radius includes an illumination optical part(20), and a measurement optical part(50). The illumination optical part illuminates various shapes of measurement lights. The measurement optical part determines an image of the measurement light. The illumination optical part includes a slit part(23), a filter part(22), and a light source(21). The slit part has at lease one slit. The filter part forms a ring-shaped image at an inspected eye. The light source illuminates a measurement light toward the slit part and the filter part. The measurement optical part includes an object lens(51), a magnification optical part(52), and an eye lens(56).
