The　titanium　anode　with　sandwich　coating　structure　was　prepared　by　a　sol-gel　method.　The　anode　was　composed　of　three　layers　by　firstly　the　oxide　based　layer　coated　with　Ti70%-Ru30%　on　the　titanium　substrate,　and　then　the　inter-layer　coated　with　Ir70%-Ta30%,　the　surface　layer　coated　with　Ti70%-Ru30%.　The　physical　and　electrochemical　properties　of　the　titanium　anode　with　sandwich　structure　were　studied　by　XRD,　electrode　potential,　polarization　curve,　cyclic　voltammetry　and　accelerated　life　tests.　The　results　showed　that　the　anode　coating　is　composed　mainly　of　rutile　phases　(Ti,　Ru)O2,　IrO2　and　amorphous　Ta2O5.　The　titanium　anode　has　excellent　electro-catalysis　activities　for　both　chlorine　evolution　and　oxygen　evolution.　In　the　electrochemical　conditions　for　chlorine　evolution,　the　anode　can　keep　better　potential　stabilities,　and　also　shows　a　strong　anticorrosive　property　for　electrolyzing　at　high　current　density　and　in　the　high　acidity.　As　the　result,　the　titanium　anode　act　as　a　good　anode　for　both　chlorine　evolution　and　oxygen　evolution.
