Can't determine candelabra type bulb
The very cleverest thing to do is to take the bulb in the picture with you to the store so you can compare it with the replacements that they have on the rack.

It can be a good idea to place the bulb in some type of paper bag wrapped in a paper towel when you transport and handle it so in case there is an accident of some sort and it gets broken there is not glass flying all over your car or the parking lot.
