Magnetic sheet and Coyle module with magnetic sheet and non-contact power supply apparatus.

摘要

Problem to be solved: to provide a magnetic sheet having stable magnetic properties and stable magnetic properties, and a Coyle module having a magnetic sheet and a non-contact power supply apparatus.Solution: the magnetic sheet 2 is composed of a sheet sintered sintered body containing Mn Zn ferrite. Residual stress in the surface layer of the magnetic sheet 2 σ S and center residual stresses σ Difference from C σ S σ The value. Vertline. Is an absolute value of 20 MPa or less.Diagram
