A self-position estimating apparatus includes a storage, a local map generator, a self-position estimator, and an adjuster. The storage stores an environmental map representing a position of an obstacle present in a mobile environment. The local map generator generates a local map representing a relative position of an obstacle present around the mobile body, with respect to the mobile body. The self-position estimator estimates, among a plurality of disposing positions on a local map disposing region set in the environmental map, one of the disposing positions where most exact matching is obtained between the local map and the environmental map, as a first self-position. The self-position estimator estimates a rotation angle of the local map at the disposing position as a first posture. The adjuster adjusts a size of the local map disposing region according to a predetermined condition.
