The wireless charging device is provided with power transmission-side pads (11, 21, 31, 41, 51, 61, 71, 81, 91) and a power reception-side pad (12). The power transmission-side pads and power reception-side pad each have a laminated core (110, 210, 310, 410, 510, 610, 710, 810, 910, 120), a powder core (111, 211, 311, 411, 511, 611, 711, 811, 911, 121), and windings (112, 113, 212, 213, 312, 313, 412, 413, 512, 513, 612, 613, 712, 713, 812, 912, 122, 123). The laminated cores are provided with a plurality of tabular parts (110a, 410a, 510a, 610a, 710a, 810a, 910a) having magnetic properties. The tabular parts are laminated in the thickness direction to constitute the laminated core. The powder core is formed on a laminated end surface of the laminated core, constituted by the laminated end surfaces of the tabular parts. |
