Abstract
An injection molding composition, having a small fluctuation characteristic and a better characteristic, is provided. The above composition is the injection molding composition comprising a ferrite powder which is a collection of ferrite particles, a first binder and a second binder. A weight and a specific surface area of the ferrite powders are represented by Wp and S, and a weight and a density of the first binder and the second binder is represented by Wb, Wb, and Db, Db. A hypothetical thickness Tbof the first binder is 2.0 to 15.0, and a hypothetical thickness Tbof the second binder is 16.5 to 32.0. In the composition, it is preferable that coated ferrite particles coating the outer circumference of the ferrite particles with the first binder and the second binder exist.1 [nm]=(1×10)/(1×)  formula (1)2 [nm]=(2×10)/(2×)  formula (2)
