  We study the thermoelectric transport through a single-level quantum dot (QD)
coupled to two normal metallic leads and side-coupled to Majorana bound state
(MBS). The Coulomb interaction in QD is considered. To investigate only the
influence of MBS on thermoelectric transport, we focus on the relatively high
temperature region ($T\gg T_K$), where Kondo effect does not appear. The
electric and thermal conductance and thermopower as a function of gate voltage
(i.e. QD level) are completely different whether the coupling between MBSs is
zero or not. When the coupling between MBSs is finite, all thermoelectric
characteristics are similar to the transport without MBS. However, for zero
MBSs' coupling, the electric and thermal conductance peaks are reduced by 3/4.
Especially, in the case of QD without MBS, the sign of thermopower changes
three times, however, in the case of QD strongly side-coupled to ideal and
isolated MBS, the sign of thermopower changes 9 or 5 times. It can be used for
detecting of the signature of MBS. It has actual possibilities when the
nanowire is long enough and pure without any defects.
