A guidewire includes a wire body having a first wire arranged on a distal end side and a second wire arranged on a proximal end side of the first wire. A proximal end surface of the first wire and a distal end surface of the second wire are joined to each other to form a joint portion. An outer member is arranged on an outer peripheral side of the wire body and forms a tubular shape which covers the wire body at least from a distal end portion of the first wire to the joint portion. An inner member is arranged between an outer peripheral portion of the wire body and an inner peripheral portion of the outer member and covers the joint portion. The inner member is an inner coil formed by winding a wire for the inner member into a coil shape.
