Claims

[Scope of utility model registration request]

Consisting of two outer legs having the same shape and the same cross-sectional area, a central leg having a cross-sectional area equal to the sum of the cross-sectional areas of the outer legs, and a common part having the same height as the outer legs. In the E type transformer core,
The outer leg is formed higher than the central leg, and the common part is provided with a notch having approximately the same width as the central leg, and the upper surface thereof is flush with the upper surface of the central leg. Features an E-type transformer core.
