Zusammenfassung:PROBLEM TO BE SOLVED: To accurately bore an insertion hole which can suck a spherical body in a previously specified position.SOLUTION: A boring device is structured so as to be used in boring an insertion hole 61 on a sheet body 60 mounted on a main body part of a spherical body suction head in a state that tensile force is applied. The boring device includes: a support part (the main body part 21, a fixing member 22, and a fixing screw 23) which has an opening part 21a, and fixes and supports the sheet body 60 arranged so as to cover the opening part 21a on a peripheral part of the opening part 21a; and a pressing part (an abutting part 31 and a pressing screw 32) which is arranged in the opening part 21a and presses an opposite region opposite to the opening part 21a of the sheet body 60 supported by the support part in a direction separating from the opening part 21a. A state that the tensile force is applied to the opposite region by press of the pressing part can be maintained.
