The mechanism of the deep earthquake that occurred south of Honshu, Japan, on February 18, 1956, has been studied by several seismologists. In the present paper, all the available data on the condensation and rarefaction of the P waves and the polarization angle of the S waves are presented. The ample data gives a fine example for the study of the source mechanism. And it is confirmed clearly that the mechanism of the earthquake can be explained by the double couple hypothesis.1956年2月18日に本州南方沖に起こつた深発地震のメカニズムはすでに多くの人々によつて研究されている.本研究においては本邦および外国の観測所におけるこの地震のP波およびS波に関する観測結果をできるだけ多く集め,その豊富な材料に基いてこの地震のメカニズムはdoub lecouple(type II)の震原モデルによつて十分によく説明できることを確めた
