Claims

[Scope of utility model registration request]

It includes a transparent envelope having a cap, a fluorescent lamp housed in the envelope, and an inductor device housed in the envelope and using a closed magnetic circuit core on one side of a circuit board. It comprises a high-frequency lighting circuit for lamp lighting, in which various circuit elements are arranged, and a conductive member having a loop shape or a shape close to a loop shape and covering the outer periphery of the high-frequency lighting circuit while housing the high-frequency lighting circuit inside. . A fluorescent lamp device, wherein the loop direction of the magnetic field focused on the core of the closed magnetic path of the inductor device among the circuit elements is made to match the loop direction of the conductive member.
