The purpose of the present invention is to reduce the occurrence of arcing during a production process, thereby improving the yield of the production process. This sputtering target is characterized by comprising a plurality of target members which are configured from a ceramic and are bonded to a base that is configured from a metal, with a bonding material being interposed therebetween, said bonding material being configured from a low-melting-point metal that has a melting point of 300°C or less. This sputtering target is also characterized in that: a surface of the base, with which the bonding material is in contact, has a surface roughness (Ra) of 1.8 μm or more; and each of the plurality of target members has a hollow cylindrical shape, while having a circular surface that faces an adjacent target member at a predetermined distance if the plurality of target members are bonded to the base so as to surround the outer circumferential surface of the base; and the circular surface has a surface roughness (Ra) of 1.0 μm or less. |
