An electromagnetic valve includes: a solenoid having a tubular guide part having the same center as a central axis extending in an axial direction; a movable element disposed inside the guide part and movable in the axial direction; a cover housing the solenoid and the movable element, defining a hole portion, and made of a magnetic material; a pin located at the hole portion and movable along with movement of the movable element; and a valve section provided outside the cover and opened/closed along with movement of the movable element and the pin. The solenoid has a core that surrounds an outer side of the movable element in the radial direction, and a coil that magnetizes the core. The core has an annular ring part surrounding the outer side of the movable element, and tooth parts protruding radially outward from the ring part on which the coil is mounted.
