A disc brake device includes flat springs assembled in a support body and holding the brake pad back plates. The flat springs have a C-shaped part provided with: a connection surface part comprising a pad-receiving surface part; an outer circumferential surface part extending along the rotor circumferential direction from the end region of the connection surface part in the rotor radially outward direction; and an inner circumferential surface part extending along the rotor circumferential direction from the end region of the connection surface part in the rotor radially inward direction. Each flat spring also has a tongue-shaped part that: extends towards the connection surface part from the tip region of the inner circumferential surface part in the rotor circumferential direction; elastically engages an inner circumferential wall of a recess at a tip region of the tongue-shaped part; and biases the pad-receiving surface part towards a base wall of the recess.
