A vaporizer having a simple structure with improved thermal efficiency is provided. A vaporizer includes a nozzle unit for jetting a liquid material in a mist state, a vaporizing unit having vaporizing paths which vaporize the material mist and form a material gas, and an ejection unit for sending the material gas to the subsequent stage. The vaporizing unit includes a vaporizing unit main body having the vaporizing paths, a main body container containing the vaporizing unit main body, a heater for heating the material mist passing through the vaporizing paths, and connecting members arranged on both end sections of the main body container. The vaporizing unit main body and the main body container are formed of a material having thermal conductivity higher than that of the material of the connecting members. The end sections of the main body container and the connecting members are bonded by explosion bonding.
