PROBLEM TO BE SOLVED: To provide a flat vibration motor which can be mounted on a device side board only by reflow processing and reduces an occupied area. SOLUTION: In a flat vibration motor, a stator board having a through-hole H<SB>1</SB>into which one end of a shaft 1 is inserted has: a magnetic metal core plate 10 having detent torque generating holes 10a to 10c, wiring patterns 30 to 39 arranged on a first electrical insulating film 20 formed on the front surface of the magnetic metal core plate, and electrode patterns 51 to 53 arranged on a second electrical insulating film 40 formed on the back surface of the magnetic metal core plate 10 and connected to the wiring patterns 30 to 39 through the through-holes h<SB>1</SB>to h<SB>3</SB>. The insides of the detent torque generating holes 10a to 10c are covered by laminated films W<SB>1</SB>to W<SB>3</SB>formed by extensions of the first electrical insulating film 20 and second electrical insulating film 40.
