Catalytic pd particles, catalytic pd powder, and method for producing catalytic pd particles

These catalytic Pd particles (1) are each provided with: a spherical core (2) including Ni and P; and a Pd plating layer (3) coating the surface of the core (2). The Pd plating layer (3) is formed as a continuous film. Furthermore, a catalytic Pd powder includes the catalytic Pd particles (1), and has a median diameter (d50), in an integrated volume distribution curve, which is at least 5 µm, but not more than 100 µm, and which satisfies [(d90-d10)/d50]≤0.8.
