To provide a lid-equipped tray from which a lid is hardly detached.
Each of zones α at the upper edges of lateral surface parts 12 and 14 of the tray 10 is formed by cutting the tray downward more than both-side adjacent zones β and γ, and acute-angle parts 16 are formed at the boundary between the zones α and β and at the boundary between the zones α and γ at the upper edges of the lateral surface parts 12 and 14 of the tray 10. An approximately-annular engagement groove 21 to be engaged with the upper edges of lateral surface parts 12 to 15 is formed at the lower surface of the peripheral part of the lid 20. The zones α' of the engagement groove 21 are formed to be shallower than both-side adjacent zones β' and γ', and steps 22 are formed respectively at the boundaries of the zones α' and β' and the boundaries of the zones α' and γ' so that the acute-angle parts 16 can be latched. In the vicinities of steps 22 at the zones β' and γ' of the engagement groove 21, the width of the bottom-part-side of the engagement groove 21 is formed to be narrower than the width of the open-side of the engagement groove 21 so that the distal ends of the acute-angle parts 16 can be positioned to be directed from inside toward outside.
