PROBLEM TO BE SOLVED: To reduce so-called sliding of a brake pad in a disc brake device without increasing the plate thickness of a plate spring to be interposed between a support and a back plate of the pad. SOLUTION: The plate spring 90 to be interposed between a recessed portion of the support and a protruding portion of the back plate includes a fixed portion 91 to be fixed to the protruding portion; an engagement portion 92 to be engaged with the recessed portion so as to be slidable in a rotor axial direction; and a connecting portion 93 connecting the engagement portion 92 to the fixed portion 91. The connecting portion 93 is formed in a flat plate shape with a rotor radial direction as the plate thickness direction and with the rotor axial direction as the plate width direction, and is linearly extended in a rotor circumferential direction except a fixed portion-side end 93a and an engagement portion-side end 93b. A pair of cuts 91c extending in the rotor radial direction is formed at a continued portion with the connecting portion 93 in the fixed portion 91, and the fixed portion-side end 93a of the connecting portion 93 is bent between the cuts 91c.
