The purpose of this paper is to clarify the influences of children's space perception on evacuation behavior in elementary school. The results are summarised as follows ; 1) Lower pupils perceive space of their school partially, upper pupils perceive the whole. 2) Children perceive the site of a fire and staircases only partially when the fire and staircases are in another wing or on another floor from the children's permanent classroom. 3) The ratio of space perception is high when the ratio of non-access route to fire is high, but the ratio of non-access route to fire is dispersive however the ratio of space perception is high.
