See the difference above. You can see that the left one is a symbol, not three symbols. Type さんてん and then hit space key, since this symbol is called 三点リーダ. (三点リーダ is usually displayed at mid-line height, as Angel Valis-san pointed out, but it's at the bottom-line now probaly due to the font this forum is using.) I usually type it by "・(/)" "・" "・" --> "space" on my 109 keyboard, though.
