Explosive nucleosynthesis under the axisymmetric explosion in Type II supernova has been performed by means of two dimensional hydrodynamical calculations .
We have compared the results with the observations of SN 1987A .
Our chief findings are as follows : ( 1 ) ^ { 44 } Ti is synthesized so much as to explain the tail of the bolometric light curve of SN 1987A .
We think this is because the alpha-rich freezeout takes place more actively under the axisymmetric explosion .
( 2 ) ^ { 57 } Ni and ^ { 58 } Ni tend to be overproduced compared with the observations .
However , this tendency relies strongly on the progenitor ’ s model .

We have also compared the abundance of each element in the mass number range A = 16 - 73 with the solar values .
We have found three outstanding features .
( 1 ) For the nuclei in the range A = 16 - 40 , their abundances are insensitive to the initial form of the shock wave .
This insensitivity is favored since the spherical calculations thus far can explain the solar system abundances in this mass range .
( 2 ) There is an enhancement around A=45 in the axisymmetric explosion compared with the spherical explosion fairly well .
In particular , ^ { 44 } Ca , which is underproduced in the present spherical calculations , is enhanced significantly .
( 3 ) In addition , there is an enhancement around A=65 .
This tendency does not rely on the form of the mass cut but of the initial shock wave .
This enhancement may be the problem of the overproduction in this mass range , although this effect would be relatively small since Type I supernovae are chiefly responsible for this mass number range .
