Abstract: An intermediate member for laser bonding (3) to be sandwiched, in order to bond a first member (2) and a second member (4) using a laser welding method, between the first member (2) made of a material capable of transmitting laser beams and the second member (4) made of a material which is the same as or different from that of the first member (2) before irradiation with laser beams, the intermediate member for laser bonding (3) having tackiness. This intermediate member for laser bonding (3) can be used for bonding of various materials, and thus a high bonding strength can be attained.

Abstract: The present invention relates to a lawn protecting method for preventing a lawn from being barren by stamping pressure, particularly relates to a lawn protecting method in golf courses, tennis courts, sports stadiums such as soccer fields and an elastic body for lawn protection used therefor. The present invention is a lawn protecting method comprising dispersing fragmental elastic bodies of not less than 0.0003 cm.sup.3 and not more than 5 cm.sup.3 in volume on a lawn or previously sowed soil, and cultivating turf. Moreover, an elastic body for lawn protection according to the present invention consists of rubber, synthetic resin or their sponge, its cross section is circular, oval, annular, spherical, polygonal and their amorphous shape, and its volume is 0.0003-5 cm.sup.3.
