Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a spindle motor having a structure which makes a conducting wire connected with a flexible printed circuit board less likely to break.SOLUTION: A spindle motor includes: a flexible printed circuit board 106 with which a conducting wire 104 from a coil is connected; and a land part 108 to which the conducting wire 104 is soldered, the land part 108 being provided on the flexible printed circuit board 106. The flexible printed circuit board 106 includes: a base part 106a; and a land part formation part 106c. The land part 108 is provided in the land formation part 106c. A narrowed stress absorption part 106b is provided between the base part 106a and the land part formation part 106c. 【課題】フレキシブルプリント基板に接続された導線の断線が生じ難い構造のスピンドルモータを提供する。【解決手段】コイルからの導線１０４が接続されたフレキシブルプリント基板１０６と、フレキシブルプリント基板１０６に設けられ、導線１０４が半田付けされるランド部１０８を備え、フレキシブルプリント基板１０６は、基部１０６ａとランド部形成部１０６ｃを備え、ランド部形成部１０６ｃにはランド部１０８が設けられ、基部１０６ａとランド部形成部１０６ｃとの間に幅の狭くなったくびれた応力吸収部１０６ｂが設けられている。【選択図】図２
