Abstract
The present invention provides a sports implement whose characteristics a user can adjust freely and minutely. According to the present invention, it is realized that a light-weight high functional circuit is installed in various sports implements by constituting various functional circuits with a TFT formed on a film, without using a printed board. A high functional circuit using a TFT formed over a flexible plastic film is light-weight and strong in bending and impacts. It is possible to provide a sports implement that is favorable in operationality and friendly to many users in a wide range regardless of the muscle strength or physical constitution and the like of a user, since the user can adjust characteristics of a sports implement.
