The object of the present invention is to decrease the brake target value from varying with respect to the braking operation with the same pedal depression force and to prevent a feeling of discomfort given to the driver during the braking operation when the braking operation has a low brake target value, which is often used by the driver under normal driving conditions. The brake control device for a vehicle includes a brake pedal 1, an electric booster 2, a master cylinder 3, a pedal depression force calculator 60, a pedal stroke sensor 18, a first target braking force portion calculator 65, a second target braking force portion calculator 66, a contribution degree setting section 63, and a target braking force calculator 67. The contribution degree setting section 63 sets the contribution degree (1-²) of the first target braking force based on the pedal depression force to be greater than the contribution degree ² of the second target braking force based on the pedal stroke when the target braking force is estimated to be low. The target braking force calculator 67 calculates the first target braking force portion and the second target braking force portion according to the contribution degree (1-²), ² and obtains the final target braking force by adding the first target braking force portion and the second target braking force portion.
