Abstract
A magnetic element including coils; a first core and a second core each of which has a planar plate portion, outer leg portions and a middle leg portion which is inserted into aforesaid coil; and an intermediate core to form a closed magnetic circuit which is disposed between the aforesaid first core and the aforesaid second core in a manner connecting integrally with the aforesaid first core and aforesaid second core. In addition, the magnetic element is made into a configuration that has relations of S1≦S3 and also S1≦S2 when a cross-sectional area of the middle leg portion of the aforesaid first core is S1, a cross-sectional area of the aforesaid intermediate core is S2 and a cross-sectional area of the middle leg portion of the aforesaid second core is S3.
