A cup-shaped part (1) having an inner peripheral uneven surface section (210) has a bottom section (11), a cylinder section (2), and the inner peripheral uneven surface section (210). The inner peripheral uneven surface section (210) has inner peripheral protrusions (211) and inner peripheral recesses (212), the inner peripheral protrusions (211) and the inner peripheral recesses (212) being formed on the inner peripheral surface (21) of the cylinder section (2). Outer peripheral recesses (221) formed by recessing the outer peripheral surface (22) of the cylinder section (2) toward the inside of the cylinder section (2) in the radial direction are formed on the base end (231) side of the outer peripheral surface (22) of the cylinder section (2). A smooth outer peripheral section (224), in which the outer peripheral recesses (221) are not formed, is formed on the opening end (232) side of the outer peripheral surface (22) of the cylinder section (2), the opening end (232) side being the side located opposite t
