Beschreibung
Zusammenfassung:	The powder material for additive manufacturing disclosed herein includes tungsten carbide (WC), cobalt (Co), and a carbon additive including carbon (C) as a main constituent element, and the value of a carbon content A (% by mass), which is represented by the following formula: [(mass of C derived from WC) + (mass of C derived from carbon additive)]/(mass of WC) × 100, satisfies the condition of 6.4 ≤ A ≤ 7.2.
