PROBLEM TO BE SOLVED: To enable rectangular pieces formed with a thin region at each of them to be engaged with each other and at the same time to restrict separation of the rectangular pieces under their engaged states.SOLUTION: A strip-shaped piece 20 acting as one example of a rectangular piece comprises a body part 21 and a male engagement part 22 arranged at one end side of the body part 21. The other end side is provided with a female engagement part 23 engaged with the male engagement part 22 of the other strip-shaped piece 20. The body part 21 is also provided with several swirl grooves 26 formed by removing its part in its thickness direction. Each of the body part 21, the male engagement part 22 and a female engagement part 23 of the strip-shaped piece 20 is manufactured by a double side etching and each of the several swirl grooves 26 is manufactured by a single-sided etching. When the two strip-shaped pieces 20 are connected to each other, the male engagement part 22 and the female engagement part 23 are engaged to each other under application of protrusions formed at each of the wall surfaces of the male engagement part 22 and the female engagement part 23 by the double side etching.SELECTED DRAWING: Figure 2 【課題】それぞれに肉薄領域が形成された矩形状片同士の係合を可能とするとともに、係合された状態での矩形状片同士の分離を抑制する。【解決手段】矩形状片の一例としての短冊状片２０は、本体部２１と本体部２１の一端側に設けられるオス係合部２２とを備えており、その他端側には他の短冊状片２０のオス係合部２２と係合するメス係合部２３が設けられる。本体部２１には、その一部を厚さ方向に除去することで形成される複数のスワール溝２６も設けられる。短冊状片２０の本体部２１、オス係合部２２およびメス係合部２３は両面エッチングにより、複数のスワール溝２６は片面エッチングにより、それぞれ製造されている。２つの短冊状片２０を連結する際、両面エッチングによってオス係合部２２およびメス係合部２３の各壁面に形成された突起を利用して、オス係合部２２とメス係合部２３とを係合させる。【選択図】図２
