Black powder, and method for producing same

A method for manufacturing a black powder comprising silica particles that contain carbon, wherein

• each of the silica particles is single-layered, and
• the content of carbon contained in the surfaces of the silica particles measured by an Xray photoelectron spectroscopy is 1% by mass or less, the method comprising:
• obtaining first particles containing a condensate that is obtained from trialkoxysilane, which is expressed by equation (1):
• R1Si(OR2)3 (1)
• (in equation (1), R1 is a non-hydrolyzable group and represents an alkyl group having 1 to 20 carbon atoms, an alkyl group having 1 to 20 carbon atoms and including a (meth)acryloyloxy group or an epoxy group, an alkenyl group having 2 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, or an aralkyl group having 7 to 20 carbon atoms, R2 represents an alkyl group having 1 to 6 carbon atoms, and OR2 may be the same or differ from each other);
• carbonizing an organic component in the first particles by heating the first particles in a gas having a lower oxygen concentration than air to obtain second particles containing carbon;
• and
• removing carbon contained in the surfaces of the second particles by heating the second particles under an atmosphere that contains oxygen.
