The objective of the present invention is to provide a self-propelled electronic apparatus which, regardless of effects of variation in the external environment while being self-propelled and heat sources in the interior of a housing, is capable of accurately detecting the ambient environment of the housing. The present invention is a self-propelled electronic apparatus which is provided with a housing (2), runs (51, 29, 26, and 27) for running the housing, environment sensors (53, 56, and 52) which detect the ambient environment of the housing, and a sliding member (2d) which is slidable with respect to the housing. The environment sensors are provided upon the inner side of the sliding member for which spaces (SL) of a predetermined interval have been formed with the housing.
