A tube-type ozone generation device (1), wherein an ozone generation unit (30) has a discharge tube (32) positioned inside an outer electrode tube (31) with a discharge gap (36) interposed therebetween. The discharge tube (32) has a dielectric tube (33), a tube-shaped electrode film (34) positioned in the dielectric tube (33), and a power-supply element (40) for supplying power to the electrode film (34). The electrode film (34) is formed by positioning an elastic conductive body (35) in the dielectric tube (33) while spirally shifting the same.
