An electromagnetic valve (100) which can ensure a predetermined response behavior while sustaining a desired control performance with operation noise being suppressed even after operation over an extended time includes a plunger assembly (15) having a plunger (7), a coil (2) for driving the plunger (7), a fixed core (4) disposed in a direction in which the plunger (7) is displaced for attracting the plunger assembly (15) to a retracted position upon electrical energization of the coil (2) to thereby hold the plunger at that position, a resilient member (8) disposed, being compressed, between the plunger (7) and the fixed core (4) to resiliently urge the plunger assembly (15) to an advanced position, and a spacer (9; 39) interposed between the plunger (7) and the fixed core (4). The spacer (9; 29; 39; 49) is provided with a protrusion (9a; 29a).
