An electromagnetic solenoid includes first and second stators arranged at two axial end sides of a coil. The first stator includes an annular radial core part, an axial core part cylindrically extending from an inner end of the radial core part toward the second stator, and a core corner part having an outer corner surface at an intersection of the radial and axial core parts. A plunger guide includes a cylindrical sleeve inward of the stators, a flange extending radially outward from the sleeve along a side of the radial core part opposed to the coil, and a plunger-guide corner part having an inner corner surface at an intersection of the sleeve and the flange. The outer and inner corner surfaces of the core corner part and the plunger-guide corner part abut on each other in a contact portion linearly or in area along an entire circumference.
