The present invention relates to a soft magnetic alloy containing: Ni, and at least one element selected from the group consisting of Al, Si and V, with the balance being Fe and inevitable impurities, in which, when the content of Ni and the total content of Al, Si and V are expressed by [Ni] and [M], respectively in mass %, and a relationship between [Ni] and [M] is plotted, the coordinate ([Ni], [M]) is present in a region surrounded by the straight lines A, B, C, D, and E.

Soft magnetic alloy

An electromagnetic valve used in a fuel system, in which at least a portion of a member constituting an magnetic circuit in an electromagnetic drive unit includes 0.15-0.45 mass % (inclusive) Ni, 0.65-1.0 mass % (inclusive) Al, 9.2-10.3 mass % (inclusive) Cr, and 0.90-1.6 mass % (inclusive) Mo, and the remainder comprises an alloy material comprising Fe and unavoidable impurities. The alloy material may further include 0.05-0.15 mass % (inclusive) Pb.

Electromagnetic valve

The present invention relates to an electromagnetic wave absorbing body which is a sheet-like electromagnetic wave absorbing body in which particles including a soft magnetic material are dispersed in a matrix including a non-metal material, in which the electromagnetic wave absorbing body satisfies a relationship: &#x3b1;&#x2265;&#x2155;, in which &#x3b1; is a parameter given by Equation (1): &#x3b1;=Ad(&#x3b5;&#x3bc;)/(&#x3bc;&#x2033;+&#x3b5;&#x2033;&#x3bc;/&#x3b5;), in which d is a thickness of the electromagnetic wave absorbing body, &#x3b5;, &#x3b5;&#x2033;, &#x3bc;, and &#x3bc;&#x2033; are a permittivity of the electromagnetic wave absorbing body, a loss term of &#x3b5;, a permeability of the electromagnetic wave absorbing body, and a loss term of &#x3bc;, respectively, and A is equal to 8&#xd7;10/&#x3c0;(&#x3a9;/m).
