Provided is a composite magnetic body composite magnetic body including a flaky metallic soft magnetism powder with a volume content of 35% or more and 55% or less, wherein the composite magnetic body is characterized by further including a phosphazene compound, a binder resin, and a phosphorus-free flame retardant auxiliary so that equations (1) and (2) are satisfied:0.17&#x2264;&#x2264;0.21&#x2003;&#x2003;(1)0.89&#x2264;(+RA)/&#x2264;2.71&#x2003;&#x2003;(2)(In the equations, PN denotes the mass % of the phosphazene compound in the composite magnetic body, RA denotes the mass % of the flame retardant auxiliary in the composite magnetic body, B denotes the mass % of the binder resin in the composite magnetic body, and P denotes the mass % of phosphorus in the composite magnetic body.) The composite magnetic body can impart high flame retardancy without losing performance such as magnetic permeability.

Flame-retardant composite magnetic body

A foot correction method comprises the steps of raising a plantar arch (15) and applying a pressure on either side of a foot (13) to thereby maintain a configuration of a longitudinal arch and a transversal arch of the foot (13) so as to prevent and correct a spraying phenomenon of the foot (13). A splint (11, 23) for practicing the method comprises shape memory alloy wires preferably in the form of either woven fabric, such as a mesh (17), or a nonwoven fabric plate. The shape memory alloy wires preferably consists of a Ti-Ni series alloy exhibiting superelasticity at a normal or used temperature.
