Abstract: A lens module and a manufacturing method of the lens module are provided. The manufacturing method includes the following steps. Firstly, a circuit substrate is provided. Then, an image sensor chip is placed on a top surface of the circuit substrate. Then, plural electrical connection paths are formed between the image sensor chip and the circuit substrate. Then, plural stacking spacer structures are formed on a top surface of the image sensor chip by a stacking process. Then, plural protective sidewalls are formed to cover the electrical connection paths. Then, a glass substrate is placed over the stacking spacer structures. Then, a lens holder structure is placed on a substrate top surface of the glass substrate directly. The glass substrate is supported by the stacking spacer structures. Consequently, the glass substrate can be maintained at the position over the image sensor chip.
