To provide a method for producing a basket-formed siloxane compound without containing a halogen component economically.

This method for producing the basket-formed siloxane compound is characterized by comprising a reaction process of reacting the A moles of a basket-formed silicate compound with the B moles of disiloxane compound in the presence of the C moles of nitric acid as a reaction catalyst. The numbers of moles of A to C satisfy 1C/(8A)3 and 1(2B)/(8A)5 simultaneously.
