A lane boundary estimation device includes: a level difference detection unit detecting a first part of a solid lane boundary; a base image setting unit setting a first image area in a most distant area in the first part as a template image; a search area setting unit setting a search area from the most distant area; and a comparison determination unit detecting a boundary candidate point for a second part of the solid lane boundary by performing template comparison in the search area. When a detection evaluation value of the first part is lower than a predetermined value and the search area includes a low-evaluation search area, the base image setting unit re-sets a second image area, nearer to a vehicle than the low-evaluation search area, as the template image. The search area setting unit skips the low-evaluation search area and re-sets a new search area.
