A thermo tea maker includes a tea cup and a tea infuser. The exterior of the tea cup has a first isolation gap in a vacuum state to block the heat conduction from an inner part to an outer part of the cup part. The exterior of the tea infuser has a second isolation gap in a vacuum state to block the heat conduction from an inner segment to an outer segment of the tea infuser. The tea cup and the tea infuser are able to keep the tea warm. When the tea infuser is turned, the tea infuser will not scald the user's hand.
