PROBLEM TO BE SOLVED: To provide a "navigation device" for presenting a recommended lane in a form for facilitating obtaining of a lane to travel when travelable lanes exist separately. SOLUTION: When one's own vehicle enters intersection 500 in the entering direction 501, and when the own vehicle arrives at a point 511 within a predetermined distance to the intersection 500 in a state where a guide route for turning left is set, a block 521 of the lane of lane number 1-2 as a lane only for turning left and a block 522 of the lane of lane number 6-7 are extracted (a). The own vehicle joins to a merge point 530 in a past predetermined travel distance from the left road as shown by a travel trajectory 510, so that the lane included in the first lane block 521 on the more left side, of the first lane block 521 and the second lane block 522, is set as the recommended lane (b1).
