PROBLEM TO BE SOLVED: To improve the core of a static induction equipment in magnetic flux loss so as to prevent its thermal loss by a method, wherein a yoke is divided into a pair of yoke piece units, irregularities are provided to the corresponding edge faces of the yoke piece units, a junction iron plate is inserted between the irregularities of the edge faces of the yoke piece units, and an iron plate connector is provided to the side of the junction iron plate. SOLUTION: A lower yoke 1d is divided at a midway point into a pair of yoke piece units 5 and 6. Irregularities 7 are provided to the corresponding edge faces of the yoke piece units 5 and 6. Iron plates 3a and 3b are laminated in layers on the irregularities 7. A projection 8 is provided to the iron plate 3a, and a recess 9 is provided to the iron plate 3b. The projections 8 and the recesses 9 are alternately provided to the irregularities 7, and a junction iron plate 2 is inserted into a space formed between the lateral recesses 9. A joint slope 4 which becomes gradually large in area, starting from its lower part toward upper part is provided to each edge face of the junction iron plate 2, and a contacting surface 10 is arranged on each side of the junction iron plate 2 coming in contact with the lateral iron plates 3a.
