| 摘要 | Provided is a hydraulic pressure control device and a braking system, which are capable of increasing a degree of freedom in layout of oil passages inside a housing. The hydraulic pressure control device includes a normally-closed type electromagnetic valve and a normally-open type electromagnetic valve. The normally-closed type electromagnetic valve includes a first valve part arranged so as to extend from a surface of the housing to an inside of the housing, and is configured to close an oil passage when a current is not supplied. The normally-open electromagnetic valve includes a second valve part being arranged so as to extend from the surface of the housing to the inside of the housing and having an axial length set to be equal to an axial length of the first valve part, and is configured to open the oil passage when a current is not supplied. | ||||||
