Imitation lawns are prevented from coming off a laying board 3 due to influence of temperature on an adhesive, secular deterioration of the adhesive, load of an external force exceeding an adhesive strength, load of a strong lateral slide force, and the like. In an artificial lawn including imitation lawns 2 , and a laying board 3 onto which the imitation lawns are planted, the imitation lawns 2 each include a bunch of foliaceous pieces 4 and a root portion 5 which bundles the bunch of foliaceous pieces, while the laying board 3 includes a plurality of root portion pots 6 into which the root portions 5 of the imitation lawns 2 are forcibly fit, respectively. A bifurcate pin member 7 having two pin tips is driven onto an upper part of the root portion 5 of the imitation lawn 2 forcibly fit in the root portion pot 6 of the laying board 3, such that the pin member traverses a middle part of the root portion, from which the foliaceous pieces 4 are parted, and strides across both sides of an opening of the root portion pot 6, whereby the imitation lawn 2 is fixed to the laying board 3.
