PROBLEM TO BE SOLVED: To provide a field emission type illumination lamp having an anode drawing structure capable of easily drawing to the outside the anode and with superior mass producibility. SOLUTION: An anode 6 and a phosphor 8 are installed on the inner face of a glass tube 4 in this order, and a cathode wire 18 is installed in the tube by fixing both ends of the cathode wire 18 to each one end side of the cathode drawing reeds 10, 12 drawn in the tube from both end side of the glass tube 4, and an anode drawing ring 20 is fixed to the tube wall, and made to be opposed to the drawn portion 12a in the tube of the cathode drawing reed 12. The anode 6 is extended to the anode drawing ring 20 and the drawn portion 12a into the tube of the cathode drawing reed 12 is electrically insulated from the anode drawing ring 20 by covering a glass pipe 24 on it.
