See https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/react/index.d.ts

Each JSX element is just syntactic sugar for calling React.createElement(component, props, ...children).

function createElement
, T extends Element>(
    type: string,
    props?: ClassAttributes & P,
    ...children: ReactNode[]): DOMElement;

So it's DOMElement
