Abstract
In a construction of a ski having patterns visible on the bottom, the sole board is made up of a transparent polyethylene resin sheet and a thermoplastic synthetic resin composite sheet sandwiched between the polyethylene resin sheet and the main body of the ski, the patterns being formed on the mating surface of the composite sheet with the polyethylene resin sheet. In manufacturing, a composite film having patterns printed thereon is successively combined with a polyethylene resin sheet by pressure fusion at high temperature. Reduced thickness of the sole board with high masking effect, omission of the wet system painting conventionally used for masking layer formation, and employment of the economically advantageous photogravure printing of the patterns can be expected.
