The invention provides a liquid composition for etching and a preparing method of a multilayer printed wiring board using the same; the liquid composition for etching can remove a chemical copper coating layer of a crystal seed layer in a semi-additive process of preparing the multilayer printed wiring board with excellent efficiency, and can simultaneously carry out compact roughtening process to a wiring surface. The etching liquid composition used in the preparation of the multilayer printed wiring board comprises 0.2-5 mass% of hydrogen peroxide, 0.5-8 mass % of sulfuric acid, 0.3-3 ppm of halide ions and 0.003-0.3mass% of tetrazoles.
