A magnetic disk drive having an electrical connection structure capable of supplying/recalling a reliable magnetic head signal. The magnetic disk drive includes an actuator arm rotatably mounted on a base, a spring arm whose basal end portion is secured to a distal end portion of the actuator arm, and a magnetic head supported by the distal end portion of the spring arm. The spring arm has a first conductor pattern one end of which is connected to the magnetic head. The magnetic disk drive further includes a main FPC having a second conductor pattern, and a relaying FPC for interconnecting the conductor pattern of the spring arm and the conductor pattern of the main FPC. The relaying FPC includes a third conductor pattern and terminals. Each terminal is constituted of a convex metal and a solder formed on the convex metal.
