In a stationary induction apparatus, an inter-partial-coil insulating plate and a plurality of inter-partial-coil spacer insulators form a refrigerant flow path in conjunction with each other. A space having an inter-partial-coil insulation dimension for withstanding an abnormal voltage is formed between a pair of partial coils. The inter-partial-coil insulating plate and the inter-partial-coil spacer insulators support both the pair of partial coils at an insulated state so as to maintain the inter-partial-coil insulation dimension. The insulators are arranged so as to be overlapped with each other in the direction in which mutually adjacent partial coils are opposed to each other.
