PROBLEM TO BE SOLVED: To provide an air purifier capable of simply forming its acicular electrode in high accuracy and reducing its production cost. SOLUTION: In the air purifier having acicular electrode lines 11 and 12 formed by arranging plural acicular electrodes 11a and 12a and a counter electrode 14 located at a prescribed distance apart from tips of the acicular electrodes 11a and 12a and in which air passes between the tips of the acicular electrodes 11a and 12a and the counter electrode 14 and also corona discharge is executed between these electrodes, the acicular electrode lines 11 and 12 are arranged in the air passing direction separated at a prescribed distance in the air passing direction and the acicular electrode lines 11 and 12 are integrated into one body with a same conductive plate 10.
