A cage net (3) includes a plurality of screen sheets (31) each having an upper section (311) and a tapered lower section (312). The upper sections (311) are interconnected side by side to form a surrounding wall (300), and the lower sections (312) are interconnected side by side to form a bottom wall (301). The lower sections (312) are folded inwardly from the respective upper sections (311) and have tapered ends extending to a substantially central part of the bottom wall (301) . The cage net (3) can be fabricated conveniently at low cost.一種箱網,包含多數網體單元。每一網體單元包括一側面部及一底面部。該等側面部彼此互相連接並圍繞形成一環形側面。該等底面部是分別自該等側面部向外延伸且彼此互相連接,並形成一底面。該環形側面與該底面相配合地界定出一容置空間。在實際製造時,只須先將該等側面部圍繞連接以形成該環形側面,再將該等底面部全部連接起來即可使用,不但可以有效地簡化製造過程,還可以降低生產時所需耗費的成本。3...箱網31...網體單元311...側面部32...掛勾33...開口34...封閉網體300...環形側面301...底面302...容置空間
