'Is webpack package included in my final react bundle.js?

I am working on a legacy project which has a huge bundle size(>10MB).To analyze the packages and bundle size I have installed danvk/source-map-explorer tool.

Upon running the tool it is showing Webpack 15.76MB in the output(screenshot attached).

is this normal ?

No, webpack is used to create the handle and shouldn't be included after bundling.
