This electric braking device is provided with: an electric motor MTR that, in accordance with an operation amount Bpa of a braking operation member BP caused by the driver of the vehicle, generates a pressing force Fba, being a force pressing a friction member MSB against a rotary member KTB that rotates integrally with a wheel WHL of the vehicle; a caliper CRP fixed to the electric motor MTR; a circuit board KBN to which a microprocessor MPR and a bridge circuit BRG are mounted, such that the electric motor MTR is driven; and a motor pin PMT that feeds power from the circuit board KBN to the electric motor MTR. The motor pin PMT penetrates a holding member HJB and is pressed into the circuit board KBN, which is fixed to the caliper CRP by the holding member HJB and the motor pin PMT.
