Provided is a self-propelled electronic device in which performance for running over a level difference of a floor surface of a room is improved. The self-propelled electronic device includes: a housing which has a bottom plate; a pair of right and left drive wheel units which support the housing; and a resilient member which resiliently urges the drive wheel units in a direction to project toward a lower side from the bottom plate, each of the drive wheel units having a drive wheel and a drive wheel holder which holds the drive wheel to be rotatable around a first shaft center, in which the drive wheel holder is attached to the housing so as to be rotatable around a second shaft center which is arranged further toward a rear side than the first shaft center and which is parallel to the first shaft center, and an urging force of the resilient member is applied to the drive wheel units such that a pressing force, which is exerted in a direction perpendicular to a straight line connecting the first shaft center and the second shaft center toward an outer periphery of the drive wheel from the first shaft center, is exerted further toward a front side in a traveling direction than toward a gravity direction of the housing.
