PROBLEM TO BE SOLVED: To provide a non-contact power transmission device capable of appropriately performing power transmission and optical communication even when first and second coils are relatively displaced.SOLUTION: A non-contact power transmission device 1 includes: a light permeable first holder 10 in which a first through hole 104 is formed; and a light permeable second holder 20 in which a second through hole 204 is formed. A first coil 13 and a second coil 23 are wound around the first through hole 104 and the second through hole 204. A first optical element 141 held by the first holder 10 and a second optical element 241 held by the second holder 20 perform optical communication with each other by using the first holder 10 and the second holder 20 as light guide paths. Thereby, the first optical element 141 and the second optical element 241 can perform optical transmission at a position for avoiding the first through hole 104 and the second through hole 204. |
