A suspension control device including an electrorheological damper, a high voltage output circuit, a connection portion, and a control unit. The electrorheological damper includes a cylinder sealingly containing electrorheological fluid, a piston, a piston rod, and a positive electrode provided in a portion through which a flow of the electrorheological fluid is generated by a slide of the piston in the cylinder, and configured to apply a voltage to the electrorheological fluid. The connection portion includes an electrode connection portion configured to connect the high voltage output circuit and the positive electrode to each other, and a ground connection portion configured to connect the cylinder and a ground to each other. A resistor member, which has a resistance value set to a load resistance value of the electrorheological fluid in a regular-use temperature range of the electrorheological damper, is provided between the electrode connection portion and the ground connection portion.
