    Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method capable of obtaining a field-emission type electron source having with excellent electron emission characteristics without requiring an annealing treatment and having long life. SOLUTION: The manufacturing method is provided with an ion implantation process for implanting carbon ions 40 at least to a tip part of an emitter 18 after forming the emitter 18 mainly composed of silicon. The coordinates of points P 1 to P 6 on an orthogonal coordinate with one axis as representing energy (its unit is keV) of the carbon ion 40 and the other axis as representing an implantation amount (its unit is ×10 17 ions/cm 2 ) are shown as (energy, implantation amount), the carbon ion 40 is implanted under a condition in an area surrounded by connecting straight lines of 6 points of P 1 (5, 0.8), P 2 (5, 1.5), P 3 (10, 2.5), P 4 (15, 3.0), P 5 (15, 2.0), and P 6 (10, 1.6).
