In an elevator car position detection device, a magnetic field generator generates an eddy current magnetic field on an identification member, and a magnetic field detector detects the eddy current magnetic field generated on the identification member. The identification member includes a plurality of conductors which are continuously arranged along an ascending and descending direction of a car, and are relatively different in a plate thickness with respect to a skin depth of an eddy current generated by the magnetic field generator on the identification member. A shape of at least a part of a boundary between the adjacent conductors is a straight line or a curve tilted with respect to a direction orthogonal to the ascending and descending direction of the car.
