PROBLEM TO BE SOLVED: To provide a gyrosensor module and an angular speed detection method for improving the detection accuracy regardless of a change in attachment angles of detection axes. SOLUTION: Since first and second offset adjustment circuits 36, 37 included in a sensor output correction circuit 32 subtract output values B1, B2 of first and second gyrosensors 10, 20 from first and second angular speedsω1,ω2 when a vehicle 102 stops, the first and second accurate angular speedsω1",ω2" can be obtained when the vehicle 102 moves. An angle between the first and second detection axes 11, 21 is an acute angleθ<SB>12</SB>. Since the first and second detection axes 11, 21 can detect the angular speedωwithin the acute angleθ<SB>12</SB>, an angle between the detection axes and an axis to be detected 60 is reduced, and a gyrosensor module 100 with the high detection accuracy can be obtained.
