AB - SuperKEKB is now being constructed with a target luminosity of 8×10³⁵ which is 40 times higher than the KEKB luminosity. The luminosity can be achieved by the "Nano-Beam" accelerator scheme, in which both beams should be squeezed to about 50 nm at the beam interaction point, IP. The beam final focusing system consists of 8 superconducting quadrupole magnets, 4 superconducting solenoids and 43 superconducting corrector coils. The QC2 magnets are designed to be located in the second closest position from IP as the final beam focusing system of SuperKEKB. The two types of quadrupole magnets have been designed for the electron and positron beam lines. The QC2P for the positron beam is designed to generate the field gradient, G, of 28.1 T/m and the effective magnetic length, L, of 0.4099 m at the current, I, of 877.4 A. The QC2E for the electron beam line is designed to generate G=28.44 T/m and L=0.537 mm, 0.419 mm (for QC2LE, QC2RE) at I=977 A. In the paper, we will present the designs and the constructions of the two types of the quadrupole magnets.
