PROBLEM TO BE SOLVED: To provide a coin-shaped detected object identification device that can suppress temporal deterioration in identification accuracy of a coin-shaped detected object and realizes a simplified configuration.SOLUTION: The coin-shaped detected object identification device comprises a first core 12 and a second core 13 that are arranged at prescribed intervals in a thickness direction of a coin-shaped detected object. The first core 12 includes protruding parts 12a to 12c that protrude toward the second core 13 and around which an exciting coil 8 is wound, and the second core 13 includes protruding parts 13a to 13c that protrude toward the first core 12 and around which detecting coils 9 and 10 are wound. A passage 5 through which the detected object passes is formed between the protruding parts 12a to 12c and the protruding parts 13a to 13c in the thickness direction of the detected object. An outer diameter of the detected object is equal to or less than: distance between an end face on an X1 direction side of the protruding part 12a and that on an X2 direction side of the protruding part 12b; and the distance between the end face on the X1 direction side of the protruding part 13a and that on the X2 direction side of the protruding part 13b. |
