A self-position estimation device for estimating the self-position of a train by comparing reference deviation data previously chronologically acquired of a characteristic change in a overhead line over a travelling train with measurement deviation data chronologically measured of the overhead line at a current position by continuous DP matching is provided with: a continuous DP matching unit (40) that calculates the position in a sequence of the reference deviation data at which the measurement deviation data matches the most with the reference deviation data by performing extensible/contractible matching with respect to the reference deviation data input by a reference deviation data input unit (10) and stored in a storage unit (30) as a database and to the measurement deviation data input by a measurement deviation data input unit (20) ; and a self-position estimation unit (50) that estimates the self-position of the train using a continuous DP matching result from the continuous DP matching unit (40) and absolute position information.
