Abstract

Provided is a friction stir spot welding tool that prevents leakage of an oil agent from a base of the tool even in a state where an axis of the tool is inclined from a vertical direction. A tool 1 includes: a pin 11; and a shoulder 12 into which the pin 11 is inserted. The pin 11 is inserted into a hollow part 12B of the shoulder 12 in a state where a pin distal end part 111 is inserted into a shoulder distal end part 121 and a pin base part 112 is inserted into a shoulder base part 122. As a result, a gap C is formed between an outer peripheral surface of the pin 11 and an inner peripheral surface of the shoulder 12. A base side surface roughness that is a value obtained by expressing a surface roughness of at least one of an outer peripheral surface 112a of the pin base part 112 and an inner peripheral surface 122a of the shoulder base part 122 as an arithmetic average roughness Ra is set in a range of more than 0.04 and less than 5.9.
