PROBLEM TO BE SOLVED: To provide a gravel mat for a water tank for aquarium fish, which can be thinned, which can hardly cause adhesion of algae and which can be easily taken out of the water tank in cleaning, and a method of manufacturing the same.SOLUTION: Silicone 12 coating the whole surface of a gravel-like body 11a makes the adjacent gravel-like bodies 11a molded into a mat-like body by being spread in the state of being connected to each other. A through-hole 16 passing through front and back sides is formed in the silicone 12 connecting the adjacent gravel-like bodies 11a to each other.COPYRIGHT: (C)2014,JPO&INPIT【課題】厚みを薄くでき、藻類が付着しにくくでき、かつ洗浄時に水槽外に取り出しやすい観賞魚用水槽の砂利マットおよびその製造方法を提供する。【解決手段】砂利状体11aの表面全体にコーティングされたシリコーン12により、隣り合う砂利状体11a同士が相互に連結された状態で敷き詰めてマット状体に成形され、隣り合う砂利状体11a同士を相互に連結するシリコーン12の間に、表裏面に貫通する貫通穴16が形成されている。【選択図】図2
