PROBLEM TO BE SOLVED: To provide a coil module capable of suppressing the power consumed by a coil in contactless charging, and to provide an electronic apparatus mounting the coil module.SOLUTION: Between a magnetic material 21 and a shield 24, a conductive member 22 having a shape larger than that of the magnetic material 21, a conductivity larger than that of the shield, and a thickness equal to or larger than the skin depth of operation frequency is provided. By providing the conductive member 22, eddy current loss occurring in the shield 24 when a current flows through a loop coil 20 is reduced, and the AC resistance of the loop coil 20 can be reduced. Consequently, the power consumed by the loop coil 20 can be suppressed during contactless charging, and thereby heat generation of the loop coil 20 can be suppressed. Furthermore, the current can be supplied more than conventional, and rapid charging can be achieved. |
