PROBLEM TO BE SOLVED: To provide a coil unit such that the whole coil can be cooled with a simple constitution.SOLUTION: A power supply-side coil unit 4 includes a coil 6 and a case 8 housing the coil 6. An outer peripheral wall 8a-2 of the case 8 is provided with an air intake 8a-4 for introducing air into the case 8 and an air outlet 8a-5 for exhausting the air from the case 8. An adjustment wall 11 is provided which adjusts a flow direction of the air introduced from the air intake 8a-4. The adjustment wall 11 has a plurality of outer wall parts 111 arranged in a polygonal shape outside the coil 6 and inside the case 8, and the air outlet 8a-5 is arranged so as not to be placed on an extension of an introduction direction Y1 from the air intake 8a-4. Consequently, the air introduced from the air intake 8a-4 and flowing in the introduction direction Y1 is made to change its flowing direction by reaching the outer wall part 111 before reaching the air outlet 8a-5. |
