We investigate γ-process during the magnetohydrodynamical (MHD) explosion of supernova in a helium star of 3.3 M_sun with including the neutrino effects. Contrary to the case of the spherical explosion, jet-like explosion due to the combined effects of differential rotation and magnetic field reduces the electron fraction significantly inside the layers. It is found that the ejected material of low electron fraction responsible for the γ-process comes out from just outside the neutrino sphere deep inside the Fe-core. This leads to the production of the second to third peaks in the solar γ-process elements. We can infer that the third peak is originated from supernova explosions associated to the jet-like explosion such as γ-ray bursts.
