かつ巻線を施したコイルボビンに前記一対のフエ
ライトコアの突き合わせ脚部を挿入してなるトラ
ンス用コアにおいて、前記突き合わせ脚部にその
突き合わせ面に向かつて狭くなるテーパー部を設
けたことを特徴とするトランス用コア。 A closed magnetic path is formed by a pair of ferrite cores,
The core for a transformer is obtained by inserting the abutting leg portions of the pair of ferrite cores into a coil bobbin on which a wire is wound, characterized in that the abutting leg portions are provided with a tapered portion that becomes narrower toward the abutting surface. Core for transformer.
