An elementary particle is one of the basic building blocks of matter.

To a first degree of approximation, those building blocks can be considered to be protons, neutrons and electrons.

Modern research in particle physics suggests the existence of smaller constituents of protons and neutrons, but at time of writing, electrons are believe to be truly, fundamentally indivisible.
