An ion generator for supplying ionized air to an intake portion of a combustion device such as a combustion engine wherein a high voltage generator (2) is disposed on the upstream side of an air flow path (A) inside a casing (1), while an ionizing electrode (3) is disposed on the downstream side of the same air flow path, wherein a gap (S) for air flowing is formed between the high voltage generator (2) and the casing (1) for cooling the high voltage generator (2), and wherein an outside electrode (31) of the ionizing electrode (3) is set to be a negative pole, while an inside electrode (32) thereof is set to be a positive pole so that the generation of plasma discharge at any portion except therebetween is prevented, whereby the high voltage generator (2) is prevented from overheating to thereby extend its life.
