PROBLEM TO BE SOLVED: To provide a relay device capable of preventing an arc short circuit between adjacent contacts having a simple structure, and capable of accomplishing miniaturization and weight reduction. SOLUTION: A plurality of fixed contacts 2 and a plurality of moving contacts 3 are arranged oppositely to each other in a case 1; the moving contacts 3 are supported by a contact displacement mechanism 4; and it is displaced by a solenoid 6 to open and close the respective fixed contacts 2 and the respective moving contacts 3. A series circuit is made to be formed when a plurality of the contacts 2 and 3 are electrically connected to each other; and the generation of arcs between the respective contacts 2 and 3 is suppressed by voltage dividing. At that time, insulating breaking walls 11 are formed between an input contact 21 and an intermediate contact 23 and between an output contact 22 and the intermediate contact 23, respectively, and the arc short circuit between them is prevented.
