  Siam Photon Source II (SPS-II) project in Thailand is the third-generation synchrotron light source. The lattice of the 3 GeV electron storage ring has been designed, consisting of 14 Double Triple Bend Achromat (DTBA) cells with the total circumference of 321.3 m. The storage ring lattice includes 56 bending magnets, 28 combined dipole and quadrupole magnets, 224 quadrupole magnets and 84 multifunction sextupole magnets. This paper presents the design and construction of a sextupole magnet prototype for SPS-II project. Magnet prototype was designed with the magnetic field gradient of 2,030 T/m2 and includes functions of skew-quadrupole, horizontal and vertical correctors. The magnetic core is made of S10C low-carbon steel. A prototype of sextupole magnet has been constructed. All dimensional tolerances are within the range of ±20 µm.
