第一乃至第八実施形態では、透明キーは、第一領域と、この第一領域を天面側から覆う透明な第二領域と、を有し、前記第一領域は、前記第二領域よりもレーザーマーキングがし易い。天面側から第一領域へレーザーマーキングしょうとすると、第二領域は透明かつ第一領域よりもレーザーマーキングがし難いので、このレーザーマーキングによる第二領域への影響は、無いか、少ないことになる。このため、このレーザーマーキングにより形成するマーキング部のキーの厚さ方向における位置は、第一領域に依存することになる。そして、キーの厚さ方向における第一領域の位置は、透明キーの構造、又は、第二領域の厚さ等の条件を変えれば、容易に決定できる。以上より、第一乃至第八実施形態に係る透明キー及びキーシートは、キーの厚さ方向におけるマーキング部の位置の制御がし易くなる。
第九実施形態では、キーシートの形成方法について説明する。ここでは、キーシートを第一実施形態のキーシート101と同様のキーシートとして説明する。
