Abstract: A soft magnetic metal strip laminate that has high adhesion strength between metal strips, free from delamination, an excellent magnetic property, a high space factor, and a process for production thereof. A process for production of a soft magnetic metal strip laminate that includes plural soft magnetic metal strips laminated by using a polyamide acid solution includes the steps of applying the polyamide acid solution on the soft magnetic metal strip, performing semicuring heat treatment to obtain the degree of imidization of the polyamide acid solution which is in the range of 15 to 70%, laminating plural soft magnetic metal strips to each other through the polyamide acid solution, and performing the heat treatment of the heating and the hot pressing to obtain the degree of imidization of the polyamide acid solution which is more than 90%.
