The convertible bond is one kind of equity-linked bonds. The term of the bond entitles bondholder to convert bonds into shares of the company or another company in the same group, at an agreed-upon conversion price, among a fixed period. The reason why it is made in this form is that the issuer can benefit from four aspects as follow,
(1) better terms. A convertible bond have a lower interest rate, less restrictive covenants or the subordination of bondholders' claims to those of other unsecuried creditors. As W Klein pointed out, the issuance of convertible bonds allows the company to raise money in a cheaper way while the company's appearance as a good credit risk will not be impaired.

Since longer conversion period gives investors a longer time to exercise the conversion right, which makes the option worth more, therefore the company can successfully issue bonds with a longer maturity than otherwise being acceptable. A longer maturity means the company will not have the pressure on reserving a great amount of money to repay in a short period, instead they can use the money for further long-term investments. In other words, the company can borrow money for a long time but in a relatively low interest.
(3) Access to investors. Due to the back-stop protection of bonds, i.e. bonds will be repay in fixed income on due date.
(4) Deferred equity financing. Issuing convertible bonds is like the shares are paid in advance.
