Abstract
Provided are an arrangement capable of reliably preventing freeze of a PCV channel without requiring additional piping and an intake manifold having this arrangement. This arrangement for freeze prevention of a PCV channel includes a PCV channel returning blowby gas containing un-combusted fuel gas as a main component thereof and leaked into an engine to an intake port, an EGR channel returning exhaust gas exhausted from the engine to the intake port, and a heating portion as a common portion between a PCV outer wall of the PCV channel and an EGR outer wall of the EGR channel.
