Abstract(in English) We improved performances of the integrated cryogenic current comparator (integrated CCC: ICCC) which was fabricated by using Nb multilayered fabrication process. The mutual inductance of the ICCC between input winding coils and a superconducting quantum interference device (SQUID) was in the range of 300 to 400pH/turn, which is comparable to those of conventional bulky CCCs, 600pH/turn. Also, winding turn errors on the order of 10^<-7> were obtained. In the future, more precise measurements are necessary. These thin-film-based ICCCs are reliable and compact, which means that they have advantages of integration with other devices using cryocoolers.
