Abstract: A baseball catcher's chest protector includes a base member, a cover member, and a cushioning member. The cover member is attached to the base member. The cushioning member is attached to the base member and is sandwiched between the base member and the cover member. The cushioning member includes a foundation and a plurality of protrusions. The plurality of protrusions protrude from the foundation. The foundation has a first surface and a second surface. The first surface faces the base member. The second surface is arranged opposite to the base member with respect to the first surface and faces the cover member. Each of the plurality of protrusions protrudes from the second surface toward the cover member and the plurality of protrusions are arranged with a space being interposed between the plurality of protrusions.

Abstract: A metal-plated carbon material includes: a carbon material; and a metal layer covering a surface of the carbon material, in which, in the metal layer, crystal grains forming the metal layer have an average crystal grain size of 110 nm or less. A method of manufacturing a metal-plated carbon material, includes: a metal complex fixation step of immersing a carbon material in a supercritical fluid or subcritical fluid containing an organometallic complex of a first metal; and a first energization deposition step of energizing the metal-complex-fixed carbon material in an electroless plating solution containing a second metal.
