PROBLEM TO BE SOLVED: To provide a method for producing a composite material having a low thermal expansion coefficient; a tabular composite; and parts for electronic equipment. SOLUTION: The method for producing the composite material with the low thermal expansion includes a process for producing a composition that contains an oxide and a metal, wherein the oxide has a negative heat expansion coefficient and is shown by the formula (A<SB>1-Z</SB>D<SB>Z</SB>)(W<SB>1-X</SB>R<SB>X</SB>)<SB>2</SB>O<SB>8</SB>(wherein A is Zr, Hf or a mixture thereof; D is at least one element selected from elements capable of being dissolved in ZrO<SB>2</SB>or HfO<SB>2</SB>; Z is a value of a maximum rate for an atom to be dissolved (0≤Z≤0.2), which is limited depending on each element; R is at least one element selected from the elements capable of being dissolved in WO<SB>3</SB>; and X is a value of a maximum rate for an atom to be dissolved (0≤Z≤0.25), which is limited depending on each element). The method for producing the composite material further includes infiltrating the molten metal of one or more metals into the oxide powder, or casting the molten metal of one or more metals that have been mixed with the oxide powder.
