It is possible to provide map information beyond a range held in a map information providing apparatus in advance even in an environment in which connection to the mobile communication network is difficult or impossible. A map information providing system S includes a map server 3 that is an external apparatus holding first map information of a relatively wide map range, a portable map transmitting apparatus 2 that downloads third map information within the range of the first map information from the map server 3 and holds the third map information, and a wrist terminal 1 that is a map information providing apparatus for providing a user with map information on the basis of second map information held in the wrist terminal. When there is a request for display of a map exceeding the map range of the second map information held in the wrist terminal 1, the wrist terminal 1 acquires map information of a map range corresponding to the request from the portable map transmitting apparatus 2 by short-range wireless communication without going through the mobile communication network, updates the map information of the wrist terminal 1 itself, and performs map display for the user on the basis of the updated map information.
