To provide induction equipment that facilitates positioning of a plurality of cores.

A projection 18 is formed at a center part of a tip surface 151 in a width direction of a center magnetic leg 15 of a first E-type core 12. The cross section of the projection 18 is rectangular. A recess 23 is formed in a center part of a tip surface 201 in a width direction of a center magnetic leg 20 of a second E-type core 13. The cross section of the recess 23 is trapezoidal. An end edge of the tip surface 181 of the projection 18 abuts against an oblique side of the trapezoid of the recess 23. Tip surfaces 161 and 221 of outer magnetic legs 16 and 22 abut against each other, and tip surfaces 171 and 211 of outer magnetic legs 17 and 21 abut against each other. The projection 18 on the side of the first E-type core 12 and the recess 23 on the side of the second E-type core 13 form a gap G1 between the tip surface 151 of the center magnetic leg 15 and the tip surface 201 of the center magnetic leg 20.
