The present invention relates to a field coil assembly of an electromagnetic clutch for a compressor, in which a coil wire of an electromagnetic coil body exposed to a protrusion of a bobbin is electrically connected with a compressing portion of a coil wire formed at one side end portion of terminals mounted inside a sleeve, and the terminals and the electromagnetic coil body are molded with the resin, thereby preventing permeation of foreign matters from the outside, preventing disconnection of the coil wires due to vibration, and simplifying a manufacturing process.
