The braking control device generates braking force by operating an electric motor to press a friction member against a wheel-fixed rotary member. The braking control device includes: a wheel speed sensor detecting wheel speed; a rotation angle sensor detecting a motor rotation angle; a drive circuit driving the motor; and a controller controlling the drive circuit. The controller sets a current limit circle within d-axis/q-axis current characteristics of the motor based on specifications of the drive circuit, calculates a voltage limit circle within the d-axis/q-axis current characteristics based on the rotation angle, executes slip suppression control for reducing the degree of wheel slip based on the wheel speed, calculates d-axis and q-axis target current values based on intersection points of the current limit circle and the voltage limit circle when execution of slip suppression control begins, and controls the drive circuit based on the d-axis and q-axis target current values.
