1. A vehicle brake device comprising:
an electric first element that adjusts braking force applied to a first wheel of a vehicle;
an electric second element that adjusts braking force applied to a second wheel of the vehicle; and
a circuit board on which an electric circuit that controls the first element and the second element is printed, the circuit board including a first sector in which a first circuit of the electric circuit that controls the first element is printed and a second sector in which a second circuit that controls the second element is printed; wherein
the first element controlled only by the first circuit is arranged to face the first sector;
the second element controlled only by the second circuit is arranged to face the second sector;
the vehicle brake device further comprises a third element controlled by both the first circuit and the second circuit, the third element being disposed so as to face perpendicular to a boundary between the first sector and the second sector or so as to face perpendicular to a region between the first sector and the second sector;
the circuit board has the first sector and the second sector arranged side by side;
the vehicle brake device includes a master cylinder device connected to wheel cylinders provided on each of the first wheel and the second wheel, the master cylinder device comprising a fluid pressure chamber defined by a cylinder and a piston such that a fluid pressure corresponding to a position of the piston sliding in the cylinder is generated in the fluid pressure chamber; and
the master cylinder device is disposed so as to face the boundary between the first sector and the second sector or so as to face the region between the first sector and the second sector.
