Patent ID: 8828264

Claim:
A magnetic sheet comprising: a binder; a magnetic powder; and a fire retardant, wherein the binder comprises an epoxy resin, wherein the fire retardant comprises at least one of a silicon atom-containing melamine cyanurate and a carboxylic acid amide-containing melamine cyanurate, wherein the magnetic sheet comprises 400 parts by mass to 1,550 parts by mass of the magnetic powder, and 70 parts by mass to 150 parts by mass of at least one of the silicon atom-containing melamine cyanurate and the carboxylic acid amide-containing melamine cyanurate, relative to 100 parts by mass of the binder, wherein the mass of the magnetic powder in the magnetic sheet is 60% by mass to 90% by mass, wherein the at least one of the silicon atom-containing melamine cyanurate and the carboxylic acid amide-containing melamine cyanurate has a number average particle size of 1 μm or less, wherein the fire retardant further comprises red phosphorus, and wherein the amount of the red phosphorus is 6 parts by mass to 19 parts by mass, relative to 100 parts by mass of the binder.
