PROBLEM TO BE SOLVED: To provide a terminal unit capable of outputting an accurate positioning result, when a last time measuring position largely separates from a true present position. SOLUTION: This terminal unit 22 has a positioning obstacle area entrance determining means for determining whether or not the terminal unit 22 enters a positioning obstacle area, a positioning obstacle area outlet position information acquiring means for acquiring positioning obstacle area outlet position information on the basis of a determining result of the positioning obstacle area entrance determining means, a positioning obstacle area separation determining means for determining whether or not the terminal unit 22 separates from the positioning obstacle area, a positioning result information generating means for generating positioning result information for indicating a plurality of positioning results of a present position on the basis of a determining result of the positioning obstacle area separation determining means, a positioning result selecting information storage means for storing positioning result selecting information for selecting a positioning result for output from the plurality of positioning results indicated in the positioning result information, and a positioning obstacle area outlet position information applying means for applying positioning obstacle area outlet position information as the positioning result selecting information.
