An electromagnetic linear valve which can effectively suppress a self-excited oscillation of a plunger is provided. A resilient member 64 urges a plunger 22 in a direction in which the core-opposing portions 70, 78 move away from a core portion 28, and moves the plunger 22 in a direction in which the core-opposing portions 70, 78 approach the core portion 28 in the case where an electric current is supplied to a coil 24. In the case where no electric current is supplied to the coil 24, a radially opposing surface area Sr as a surface area of portions of the core-opposing portions 70, 78 which respectively oppose inner peripheral surfaces of recessed portions 74, 76 is smaller than an axially opposing surface area St as a surface area of portions of the core-opposing portions 70, 78 which respectively oppose bottom surfaces of the recessed portions 74, 76, and the radially opposing surface area Sr becomes larger than the axially opposing surface area St in the case where an electric current is supplied to the coil 24 and the core-opposing portions 70, 78 approach most to the core portion 28.
