Abstract: A brake device is characterized by being provided with an auxiliary pressure source 100 that accumulates a predetermined range of brake fluid pressure in an accumulator 102 on the basis of an operation of a fluid pressure pump 101, and that outputs the brake fluid pressure as an accumulator pressure; and an electromagnetic valve 110, 111 that controls blocking of communication between the fluid pressure pump 101 and the accumulator 102 and a main pipe line, and that transmits the accumulator pressure to a wheel cylinder when placed in communication state.
