A　scheme　is　proposed　to　generate　W　state　with　qubits　of　superconducting　quantum　interference　devices　(SQUIDs),　based　on　adiabatic　passage　along　dark　state.　Taking　advantages　of　adiabatic　passage,　the　scheme　is　very　robust　against　decoherence,　and　it　does　not　need　to　control　the　classical　field　and　the　interaction　time　accurately.　Because　of　the　achievable　strong　coupling　between　SQUID　qubits　and　cavity,　W　state　can　be　generated　with　high　successful　probability.
